If you're going the solid wood route it's definitely best to use a vapor barrier / isolation membrane and add a subfloor you can nail into. I would also consider keeping it unfinished. I find that the engineered hardwood is a little slippery once it gets sawdust on it.
i’m pretty sure when I talk to our builder and we talked about nail down solid wood floor inside. He was putting down at least a vapor barrier and then something else. It was just cost prohibitive after finishing it, etc. The garage is a whole different animal as it’s only 550 ft.². I agree keeping it unfinished I think the dings and the eventual scuffs, etc. simply add a little charm to the whole environment if I go that route.
