If I were in your position, I would wire for 2 circuits. 1 100amp breaker circuit for 80amp charging (wall charger) and a 50amp circuit for back up. Assuming you have the room in your panel for 2 additional circuits
This is exactly what i did. The HPWC is hard wired to the panel (via cutoff switch) and there is an empty 50A outlet next to it as backup in case the HPWC unexpectedly is unavailable or something non-Tesla plugs into it (future proofing).
