The strike hit before all 26 TNG season 1 episodes could be filmed, so earlier draft scripts were used. The TNG Companion goes into Rick Berman trying to elicit episode revisions from Hannah Louise Sheerer for "We'll Always Have Paris", and "The Neutral Zone" famously filmed the first draft Maurice Hurley knocked out in 24 hours. So the show didn't exactly shut down, it just had a longer production hiatus between seasons 1 and 2. Much like SNW season 3 did with the latest strike.
The early arc from DISCOVERY season 2 was reshot to remove the Pike as a devout Catholic plotline. There are Deadline articles going over the shut down and reshoots when Alex Kurtzman took over as showrunner from the fired Harberts and Berg and reconfigured the season arc.
PICARD ran around 30 days over pattern in shooting season 1 according to public records in California. There are interviews with various actors talking about doing reshoots for the beginning of the season at the end of production.
No reshoots have been established for SNW. It's had a much more stable production history than the two former series.
Both TNG and DISCOVERY / PICARD both had their issues, but DISCOVERY / PICARD quantifiably had more than the former.
