I'd agree with the gravitational drive method. That way we could accelerate to near the speed of light, and quickly. Of course there is no technology
to do this currently, but it what we would need for interstellar travel.
As for Oxygen, food, and water, we would need something that would turn our waste back into useable materials. Something that can molecularly rearange
CO2, into Carbon and Oxygen, same thing for human waste, filter out the water, then molecularly rearange the solid waste back into a suitable food.
Using plants or a Biosphere type thing would be to fragile for longterm space travel.
As for the people on board, i would say either a form of stasis or just live on the ship so that future generation can reach the destination.
Any long distance interstellar travel would have to be more of a traveling mini-world more than just a vehicle to go from one point to anoher.
I honestly think humans, if we survive long enough, will have a mean of travel we can't even contemplate yet.
