Completed an entire building out of autoclaved concrete in 2004.
I specified it once. Haven’t used it again. It’s basically concrete EIFS. My panels were 8” thick, and we could fairly easily penetrate thru it.
CIP reinforced concrete is going to be the OP’s best construction type. Use of ICF (insulated leave in place) forms is a reasonable solution too.
Again, actually designing the reinforcing is key. If it were my residence, I would design to commercial standards. Virtually every One and Two Family Dwelling Code ('residential building code') I’ve reviewed (example: IRC) grossly under represent lateral load resistance, etc.
