Echoing move to SNW. It has a higher budget than older Trek and follows the current trend of “mini-series” storytelling. Older Trek follows older TV rules (wanted 26 eps to a season so a lot of filler to make it so). DS9 would be my other rec with a heavy caveat that if you’re not feeling an ep skip it and look it up on memory alpha later, particularly for the first season. As it goes on it gets more into the long form storytelling you’d expect with today’s shows, but first few seasons can be a bit rough and there can be a long time between plots being revisited (but when they are they make it count). TNG, Voyager and TOS are mainly monster/problem of the week (Voyager kind of weakly straddles longform and episodic leaning heavily towards episodic). Out of them I’d recommend TNG outside of the first two seasons (first season is TOS scifi tales encore, second season I actually like a lot and has some good eps, but general like is a minority opinion and cast gets retooled in third season anyway).

If you don’t mind kids shows also recommend Prodigy (kinda like a Trek ATLA imo).
