Accelerating a probe to ~0.5c isn’t the biggest issue. It will be much harder to deaccelerate once you are at the target location.
I think the expansion of the universe means you don’t have to deaccelerate.
For some destinations, but not for most of them (I’m pretty sure). At least Eternity in Six Hours spends a great detail of time discussing deceleration.
If you wouldn’t fly faster then a given universe moves, I don’t see how you can ever catch up to the universe.
It’s a question of acceleration, not just speed.
