Barndominium/Shop or "real" House?

Are you going to install the insulation yourself? Cutting and fitting it into those cavities is not going to be fun.

Not sure. I've been deciding as I go along what tasks I do myself. I've done insulation before so can do it, but just like drywall I hate doing it so hopefully can find someone to get it done in the timeframe I need.

If it’s not too late I would dig a small footing on the perimeter to allow for a thicker edge with a couple bars of # 4 in it. It serves two purposes. First it keeps the material under the slab from migrating out leaving a void and the increased strength is needed on the edge since tires put 100% of their weight there until they get further out to gain a larger support area.
I have been doing it for over 50 years since I started. Learned the hard way. I have poured over 450 yards on my home project around here and did my last about 6 months ago when the price reached $200 per yard. Thanks to CA politicians and their environmentalists

You might also think about some decorative work outside. I stained my porch to go with my stone work and I have more to do.
