Home Charger for 3 SR+

He did ask for me to find out what the best adapter would be for the tesla and he will put that recepticle in for me. I am thinking 6-50?

Personally I'd go NEMA 14-50. It won't make a difference in your house, but it will make a difference in the usefulness of the extra adapter you'll have to buy for your UMC when you go somewhere else -- the car is unfortunately only sold with a UMC with the NEMA 5-15 (120V household plug) adapter, so you'll have to get an adapter. If you get a 6-50 adapter chances are that it won't be very useful out of your home (especially if you're not electricity-minded).

If the extra cost of 14-50 wiring for your house is more than the cost of the 14-50 adapter for the UMC, I'd buy both the 6-50 and 14-50 adapters for the UMC and install 6-50 at home.

As a general rule of thumb, the current load should be 80% of the circuit breaker/wire

It's not just a good idea, or a rule of thumb, but a hard requirement of the NEC. EV charge current must be limited to 80% of circuit rating, no exceptions.

If the extra cost of 14-50 wiring for your house is more than the cost of the 14-50 adapter for the UMC, I'd buy both the 6-50 and 14-50 adapters for the UMC and install 6-50 at home.

This. The cost difference of just 50ft of wire is enough to fund an adapter purchase. I wouldn't worry about charging at RV parks; you're unlikely to ever need it. That's a vestige of the old, pre-supercharger world.

Given I am as old as I am and have never been to an RV park in my life, I am thinking this is not a consideration for me
