I'm aware that the most highly regarded option for an interstellar trip that takes more than one lifetime is to either cryogenic-freezing or to carry the embryos, in both cases the process being supervised by robots, with a preestablished order of waking up or letting the humans grow when it approaches a planet. This means that the author will skip the travel, as it is an automatized process without relevance.
Ultimately the concept of sending people to space knowing that them and many of their successors won't be able to touch ground, while the 2 other options exists, is unethical. Nevertheless, I feel like it is an interesting case scenario and no books of such thematic come into my mind.
I don't care if it's a romance or comedy-drama of the astronaut's everyday life, an adventure in which they encounter navigation problems and have promises on exploring the galactic phenomena, an Among Us type of murder mystery, with the last 2 having actual stakes of the ship never getting to its destination, or any in-between of the above. I will gladly contemplate any book on interstellar intergenerational travel you suggest.

Project Hail Mary by Andy Weir touches on the vibe you are interested in, but is not completely on par. Regardless, it is an incredible journey that is worth checking out.
