Benjamin Sisko returns from the Celestial Temple to Deep Space 9 in 2378, and his daughter is named Sarah. In DS9 - Unity, he arrived on Bajor in 2376, and his daughter is named Rebecca.
The U.S.S. Theseus was previously introduced in the same authors' Year Five #13 to #14. Its dossier uses the designation Discovery class, which was used by the games Star Trek: Legacy and Star Trek Online for different purposes, the latter in particular collaborating to introduce the 2022 IDW design as named the Theseus class in 2023.
Montgomery Scott is indicated to have been working on rebuilding the U.S.S. Theseus (because the authors insisted on a pointless homage to the Ship of Theseus thought experiment) since 2370. In the SCE series, Scott headed up the entire SCE for most of the 2370s.
Sisko served with Eshrine, one of the fathers of Lily Sato, aboard the U.S.S. Okinawa during the Tzenkethi War. In Typhon Pact - Rough Beasts of Empire, the Okinawa crew lineup was different. Implicitly, the Andorians in this continuity are not quad-sex for reproduction as in the First Splinter, but this is not clarified.
In 2378, Theseus finds a group of crystalline entities just as they fall to the yet-unrevealed godkiller. Sisko classifies the tragedy as genocide, and while the term does not require 100% saturation, the writing feels at odds with the rest of Kurtzman canon, wherein the U.S.S. Cerritos casually encounters several crystalline entities circa 2381 in LD 2.08 "I, Excretus". By contrast, Titan - Orion's Hounds has William Riker imply Starfleet to have no knowledge of crystalline entities in groups until 2380.

Kahless II is hostile to the Federation when Worf brings the Theseus crew in to see him. This is a vastly different depiction to the First Splinter, wherein Kahless is in very good association with the Enterprise-E crew in TNG - A Time for War, A Time for Peace and the Prey trilogy. Interestingly, despite many instances in the series of characters arbitrarily having special knowledge, the Memory Alpha diplomatic briefing in this issue indicates Starfleet at large does not know about the time crystals on Boreth as depicted in DIS 2.12 "Through the Valley of Shadows", instead merely attributing the rebirth of Kahless to advances in cloning technology.
The Memory Alpha diplomatic briefing names the Chancellor as Martok as the son of Urthog. This name for Martok's father was first given in DS9 - The Left Hand of Destiny.
Worf gets himself reinstated to Starfleet because he misses Starfleet. As it happens, TNG - A Time for War, A Time for Peace depicted him undertaking a similar decision in 2379.
2023.01.04 - Star Trek #3
T'Lir's personnel file names their parents as Sovan and T'Lai of Da-leb Kinor (not sure if that is a typo of "Minor"). The city Da-leb comes from the 1998 Last Unicorn RPG module "The Way of Kolinahr: The Vulcans".
At age 18, T'lir received the Graf Award. This might be an homage to the joint novelist pen name L.A. Graf.
Jake mentions that his grandfather has passed. In the First Splinter, Joseph Sisko died in 2381, as mentioned in Typhon Pact - Rough Beasts of Empire.
2023.02.01 - Star Trek #4
An LCARS file on the T'Kon states that the location of their supernova-devastated homeworld is unknown. In the Vanguard novel series, this core system is known in the 2260s to the Federation as Eremar.
Thomas Paris refers to himself as the son of Julia Paris, the name of his mother first being given in VOY - Homecoming.

Kahless II posses the Bajoran Orb of Destruction, an orb name never used previously in other media, which have different lineups for the 10 or so orbs.
2023.03.15 - Defiant #1
Spock is using the planet Chaltok IV, mentioned in VOY - "Time and Again", as a meeting ground for the reunification movement. In the First Splinter, Spock was mostly based on Romulus until 2383.
In VOY - Homecoming et al., Starfleet had integrated the former Maquis into the relaunched Voyager. Here, B'Elanna is unhappy with Starfleet treating her and everyone as untrustworthy Maquis rubbish.
Tom asserts that B'Elanna is not like her mother, who apparently died in VOY 6.03 "Barge of the Dead". In VOY - Homecoming and The Farther Shore, Miral turned out to be alive on Boreth only to die immediately after being reunited.
In DS9 - Avatar et al., Ro Laren joined the Bajoran Militia after the Dominion War, and eventually rejoined Starfleet. Here, Ro is serving a life sentence from the Federation when Worf breaks her out to serve in his operation. In the concurrent PIC 3.05 "Impostors", Ro states that her prison sentence from the Federation was commuted in exchange for her expertise in dealing with militant groups. I guess the IDW depiction is supposed to lead into the Kurtzman canon depiction, though it stretches credulity that Worf spends over 20 years never informing Picard about meeting Ro again.
Worf and co. steal the newer U.S.S. Defiant from a drydock where it has been since the end of the war. A Starfleet communique notes that despite the resumption of the Treaty of Algeron, the Defiant has a cloaking device, though how is not explained given the previous ship was blown up. In the First Splinter, the Defiant never left service in defense of Deep Space 9, and was intentionally given a second cloaking device by the Romulans to replace the lost first one.
To my disgruntlement, this series follows every canon and non-canon series in recycling the registry NX-74205 for the newer Defiant even though the DS9 producers acknowledged this was a budget-saving footage limitation of the final TV episode.

The U.S.S. Theseus is equipped with a classified proto-warp propulsion system, evidently an earlier version of the one on the U.S.S. Protostar in Star Trek: Prodigy.

It is explained that after being defeated and disassembled in TNG 7.01 "Descent, Part II", Lore's parts were sent to be studied by Section 31 at the Dead Moon 1 facility, from which Worf's crew reactivated and reassembled him. This more-or-less works with PIC 3.06 "The Bounty", wherein Section 31 had some jurisdiction over the salvaged first-generation Soong android parts.

This issue includes a transcribed special report on the 10 orbs in this continuity. They are Contemplation, Time, Prophecy & Change, Wisdom, two redacted entries, two unknown entries, Destruction, and of the Emissary.
Shaxs is the only Bajoran member of a Federation taskforce to recover Bajoran artifacts. His first lead is that the Cardassians still possess the remaining stolen orbs, but Cardassia Prime has been off-limits to outsiders for the three years since the Dominion War ended. In the First Splinter, the Federation was heavily involved in relief efforts on Cardassia Prime for many years following the war. Yevir Linjarin even traveled to Cardassia Prime in 2376 to recover four lost orbs.
A historical note from Memory Alpha says Benjamin Sisko narrowly beat Garth of Izar as the most decorated Starfleet officer in history. The note also refers to Garth as a Klingon War hero turned rogue despot; how that figure is qualified is unclear as Kurtzman-era canon implies not even the Battle of Donatu V in 2245 was considered a full-scale war. For its part, TOS - Garth of Izar indicated Garth's descent into madness to have transpired circa 2251.

The U.S.S. Santa Cruz is a Shikahr-class vessel, a class introduced in Star Trek Online. Oddly, it has a name more apt for the contemporary California class.
2023.05.10 - Defiant #3
The newly-introduced Orion medic thinks of a story told by her grandmother about an Orion blood feud with a Gorn commander from a few centuries ago. This would fit with ENT 4.17 "Bound", wherein Harrad-Sar has a beverage brewed by Gorn, but how it fits with SNW's depiction of the Gorn is questionable.
2023.05.17 - Star Trek #8
Elim Garak is on Cardassia Prime, similarly to what the First Splinter also presumed prior to Garak's career as Cardassian Ambassador to the Federation.
First Speaker Barada Damar is the nephew of the late Legate Damar, who is not specified to be named Corat as in DS9 - A Stitch in Time, which implied the Dominion successfully got to any and all of Damar's relatives.

The holo-strike aboard the U.S.S. Theseus in 2378 is quite the different result of Photons Be Free compared to Oliver Baines's failed holo-revolution in VOY - The Further Shore.
2023.06.07 - Defiant #4
According to a text transcript, Admiral Edward Jellico debriefed B'Elanna Torres upon her return to Earth. In VOY - Homecoming, Jellico was not involved in the debrief of the Voyager crew.
B'Elanna Torres found out about Korath. According to VOY - Homecoming and DTI - Watching the Clock, the alternate Admiral Kathryn Janeway never got around to telling anyone about Korath.
Korath's private laboratory is located on Maranga IV, featured in TNG 7.21 "Firstborn". In DTI - Watching the Clock, he hails from the Cambra system, which was mentioned but not seen in "Firstborn".
The Chaffee is stationed aboard the newer U.S.S. Defiant, implicitly salvaged from its destroyed predecessor. In the First Splinter, the Chaffee was also salvaged for reuse aboard the new Defiant.
Sela's depiction in this continuity is obviously different from the First Splinter and Star Trek Online. Here, her failure in TNG - "Unification" got her reassigned to a backwater sector for the duration of the Dominion War. TNG - Triangle: Imzadi II and NF - Double or Nothing had her doing some important things during the Dominion cold war, and then escaping Federation custody off-screen to become important again by the time of TNG - Death in Winter.

Yeor assassinates the purportedly last Founder left in the Alpha Quadrant. In the First Splinter and in Kurtzman canon, various Founders were doing various things on their own in the Alpha Quadrant after the war.

The capital of Romulus is Dartha, a name first given in the TNG - Unification novelization. In Titan - Taking Wing, Tuvok learned Dartha had been renamed Ki Baratan some time prior to the Shinzon coup against Hiren in 2379.
Korath's chrono-deflector is already (somewhat) functional in 2378. In DTI - Watching the Clock, the chrono-deflector is only a loose idea in 2382.
Sela lands in the incident when prime Natasha Yar saved refugees from Carnelian mines, as mentioned in TNG 2.06 "Legacy". Here, Jean-Luc Picard commands the U.S.S. April. TNG - The Buried Age depicted a different version with Carnelian as the demonym for the multispecies Regnancy of the Carnelian Throne, and Picard was based on the U.S.S. Cybele.
