Some books with this concept or similar
-2001 space odyssey (not as far in the future but has the concept of humanity transcending itself which is my favorite type of speculative fiction, but i am down for very negative interpretations too)
-three body problem doesnt really count and i have a lot of problems with it but the far reaching ideas and the political subplotlines were cool)
-alistair reynolds revelation space this is probably my favorite book series of all time and the conjoiners are the best
-a short story that i cant remember the name of about a generation ship in which some people have to choose to augment themselves in order to be imortal and then they reach the planet and i think they just keep going and going until eventually the main character is this ethereal entity that can pretty much exist anywhere in the universe and i think they start their own race of humans or something idk im misremembering and maybe even mixing up 2 or 3 stories

Do Androids Dream of Electric Sheep?, Foundation series or Robot series
Maybe the Wayfarers books by Becky Chambers
Enders Game.
The subsequent books are set literally thousands of years later.
