I've heard "The Expanse" and "For All Mankind" are supposed to be good TV shows, but I haven't seen them yet.
If you've already read most of the well-known ones, I could give you some recommendations from less well-known authors and self-published authors you probably haven't heard of yet. Though it would help to have some general direction of what you're looking for (military/space opera/other, ftl/aliens?, etc). Allowing for limited FTL handwavyness opens up a lot of space opera titles that elect to otherwise play by hard sci-fi rules.
* Some may recommend "Pushing Ice" over this one for being more "hard" sci-fi, but personally House of Suns was a much more satisfying read.
- valuable humans in transit by qntm
- the old axolotl by Jacek Dukaj (skip the tv show, it is very different from the book)
- the Agent Cormac series by Neal Asher
- the night’s dawn trilogy by peter f hamilton (his books are borderline fantasy, but he writes such deliciously monstrous villains)
