Do not think in terms of what is the bare minimum you may be able to get away with in the most optimal of conditions. People don't come home and depart at the exact same time every day with zero surprises. Sometimes you'll forget to plug in; sometimes you'll need to leave early. So you'll want as much reasonable charge as you can get. 48 amp AC chargers seem to be the sweet spot for most homes and commuters.
Teslas today have a max home-charge-rate of 48 amps (11.5 kW). There were some earlier model S and X that could go up to 80 amps (19.2 kW), but the new ones today only do 48 amps.
There's also a lot of debate around whether you would want a dedicated wall charger or just get a NEMA outlet and plug in. There is no consensus here... some people just want to charge with the least amount of investment possible. Some people want a charger that they feel is a fixture totally intended for EV charging. So my recommendation is to pick the camp that is right for you (NEMA outlet or EV wall connector) ... and get the desired hardware installed by an electrician in your garage.
As far as I can tell, nobody out there that drives their EV every day is happy with charging only on a 120v outlet.
