Would there be any benefit to using a bigger ground wire (1/0) than power wire (4 gauge)?

Not really. As long as your poer wire is the correct size, then just use the same size ground wire.

technically it would present less resistance.

but going from a very low resistance to even LESS would make no difference at all.

you shouldn't do the opposite however. your ground can be the same size or bigger, but the power wire should be the same size or smaller.

yeppers. i am also a fan of running a full ground back to the battery itself. alot easier if you have the battery in the trunk.
