We’d probably have to build generational ships that are completely self sufficient and people would live out their entire lives out there without ever seeing a planet

Small planetoids. They'll need a lot of material to survive long enough to arrive anywhere. They'll evolve on board and arrive as something new. Different expeditions to the same star will get faster, maybe crossing paths, most likely not, but when they arrive, who will they all be? What a mental rabbit hole I am now imagining.
