Not necessarily, Pocket has relased a TNG, and a DS9 novel over the last few years, and IDW has been releasing TNG, DS9 and Voyager comics. They're in the midst of a Voyager: Homecoming comic, which is a new version of Voyager's return home that has nothing to do with the novel of the same name.
I haven't read that one, but I just finished rereading their last Voyager comic, Seven's Reckoning, which was really good. Their most recent DS9 comic, The Dog of War was absolutely fantastic, I especially recommend it if you're a dog person.
IDW has also been doing their own original series, like the crossover Star Trek (no subtitle) ongoing series and it's Defiant spinoff. The main series focused on Sisko, who returns from the wormhole and puts together a new crew consisting of himself, Worf, Data, Crusher, Paris, and Scotty. It then spun off into the Defiant series, which featured Worf, Ro Laren, Lore, Spock and I think Sela. I haven't read them, but they do have their fans.
They're also currently doing a Red Shirts series, which focuses on an original Orignal Series era Red Shirt officers on a dangerous mission involving spies. This one does get pretty gory at times, so if that isn't you're thing you might want to avoid it.
I noticed you didn't mention Lower Decks, and as a huge, HUGE fan of that series, I'd highly recommend the Lower Decks comics. The first miniseries, and the early issue by Ryan North are absolutely fanatastic, and the more recent issue by Tyler Sheridan haven't been quite as good, but definitely still worth reading. North also wrote the first ever "interactive graphic novel" for Trek, Lower Decks: Warp Your Own Way, which won the Hugo Award for Best Graphic Story, and it is absolutely amazing.
