Thanks for the input, folks. Really appreciate it.

I REALLY like the idea of the mini-split. Will be looking into that one some more!

Shop is 30x30' two story, detached from the house and currently almost completely uninsulated. Obviously insulation is a HUGE priority to make any kind of difference with heating or cooling. It's on the list.

Fired off an email to my insurance agent re: wood and pellet stoves. Will see what comes back.

Thanks again, everyone.
