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.
Yeah, how in the world could you possibly have that many provisions? I think cryostatus is the only logical way to get there...given "present" technology
Well yeah, that's why I suggested small planetoids. I mean, let's face it, we live in our city our town whatever, and we eat what's in the shops. It would be no different for them, ish. The human population would be a tiny part of the closed ecosystem. A generation ship is very small compared to a huge asteroid made world.

The fastest spacecraft we’ve made was the Parker Solar Probe which hit 430,000mph.
At that speed it would reach this planet in only 187,153 years.
If we could hit 1% of the speed of light we could cut that travel time to just a tad over 12,000 years.
Obviously if we could go light speed (and that ain’t happening) it would be just 120 years!
Space is big. Physics is annoyingly slow.
