In the following video I am comparing the heat loss while charging at around 3kW to charging at 11kW.
I calculate that in Europe even at 13A 230V will give you only 10% disadvantage over 11kW. In the US at 7kW 14-50 NEMA is going to be even less of a heat loss difference to a Tesla wallbox.
So a (Tesla) Wallbox 11kW doesn't make any sense regardless of geographical locaiton.
My advices based on both videos:
1) In USA - Nema 14-50 is the best choice as it is cheaper and the difference of about 4kW is negligible.
2) In Europe you can go by with Schuko (3kW) and for most countries you will need to charge your car for 200,000-300,000km at home alone (if you supercharge, that number increases even further) before a wallbox pays for itself. If you get a Blue 3.7kW adapter, the heat loss is even less.
Either way - you will be better off to get the extra cash and install a few extra solar panels on your roof.
