My parking area around the front of the house is 6" thick, 5000 psi concrete with rebar, sitting on 12" thick gravel bed. And that's 50 yards of concrete.

There’s no impact if your driveway heaves other than cosmetic. If your garage heaves if could have some major issues. Especially if it doesn’t displace evenly throughout.
On the design. I assume you are referring to footer interchangeably with what I’m calling chain wall. You are probably on the right path. Just remember there is such a thing as too much rebar. The concrete code has both a Amin and Amax for steel area in a slab.
