Let me play the devil's advocate for a moment.

Ever consider using T&G siding.

Relatively low cost, you won't punch holes thru it, and you can pretty
much hang anything you want, anywhere you want.

Be a good idea to rough in the electrical under the siding under the
wall covering, whatever you use.

BTW, not my idea, NYW had project building a workshop in a garage that
used it.

YMMV.
