AFAICT, you can't break anything by miswiring; you'll just end
up without some capability (no heat, no ACbrrr, CONTINUOUS heat,
etc.)

Wire it so the A/C compressor runs constantly without the fan. Would that do it
(break something)?

But you would know "something is wrong" as soon as you turned
everything on. It's not like you're going to blow a fuse
or cause the furnace to run without the blower, etc. (thereby
catching fire in short order).

By contrast, consider what happens when you wire an electrical
outlet wrong (put HOT on the terminal associated with earth
ground).
