Look at Bussard Ramjet. Why would you carry your fuel with adequately advanced technology (let alone zero point quantum stuff)

Shields are much more interesting near c.

Shields are another thing: How do you protect your hull from the protons that hit it at relativistic speed?

Any problem is solvable with unlimited energy at your disposal. Protons are charged so you divert them with an electric field. If you’re using a ramjet for propulsion, you collect them to fuse. The incoming velocity could be a benefit there.
