You’ll find some people advocating for 10AWG for everything, but if it’s me doing the work, I only use 10AWG when I have to. The stuff is an absolute PITA to work with. I’d plan on one or two 10 gauge circuits to feed the mini split system (though I don’t know how much current those typically draw), and possibly one to feed a dust collector if you have a 5+ HP system. Otherwise you’ll be fine with 20amp circuits fed by 12 gauge wire.

There’s a small amount of future proofing with 10 gauge wire and 30amp circuits. Whether or not that’s worth anything to you is a question only you can answer.
