Have you heard of
solosider? If I ever had to hang hardi alone that's what I'd try using. Might be worth looking at.
Also you mentioned having it well insulated to allow solar heating/cooling. Reducing air leaks goes a long way in reducing the heating/cooling loads. Sprayfoam insulation also seals cracks, so that will make your walls airtight. If you're blowing in cellulose in the attic, you'll want to detail all the cracks and joints for making them airtight. An easy method is to spot spray critical areas with spray foam.
Cracks at high and low areas are more of a problem, as stack effect pressure increases air leakage through these points. Also, if you use any fans for HVAC/ventilation, it's best to balance them so there isn't any net negative/positive pressure on the envelope. I suspect the large garage door will be tough to make air-tight.
At the start of the thread you wrote there's 2" XPS between the slab and block wall, I assume that's at the slab edge, so you can see the top of that insulation when you're looking down along the floor perimeter? How is the short block wall itself going to be insulated?
