The sensible thing to do for this panel would be to have a 40 A 220V
circuit for this panel, protected at the main panel by a suitable
breaker.

This is the second or third time you've said this and it's just wrong.
There is no reason it cannot be on a #12 wire protected by a 20A breaker.
It's no different than your house wiring.
