Cost is no object and I really want NM: $6/foot But if you really want to, take the sizes above, subtract 2 numerical sizes (#2 becomes #4) and triple the price LOL. If you want to do the sub panel as in option #1, and use copper feeder, well, it's wasted on the sub-panel's aluminum lugs (AL lugs are the universal donor, playing well with Cu). This can run direct to the Wall Connector's terminals. If you want to run copper direct, and you can avoid using NM or UF type cables, then you can run #6 copper (65A at 75C thermal, which NM and UF are not allowed). Cost is no object, and I prefer copper: $4/foot I guess they figure you're buying an $80,000 car. You would need to use three Polaris connectors to "pigtail" the aluminum wire to copper wire, since in a glaring oversight, Tesla failed to make their Wall Connector lugs compatible with aluminum. For this your minimum size is #4 aluminum (65A). You can also run aluminum without a sub panel, just to the Tesla Wall Connector. Forget the sub panel, $1.20/foot + $40 once Aluminum is cheap, and perfectly safe in heavy feeder applications like this. So figure out what combined ampacity you would want and run that. So that lets us run aluminum feeder, which saves a fortune. One of the nice thing about subpanels is they have lugs appropriate for aluminum wire ( made of aluminum actually). I don't fool around, I think 24-30 spaces is a fine panel size for a garage. Unfortunately most people chintz out on panel spaces, so most subpanels are full. That will allow you to consolidate all other loads in this area to this sub panel - which I remind you is legally required if this is an outbuilding! If there is an existing sub panel and it has enough spaces, just enlarge its feeder.

Since you specified a costly 3-wire (w/ neutral) feeder for some reason, you might as well get full bang for your buck and feed a sub panel. With a built-in Wi-Fi connection, it is possible that the famous Destination Chargers could appear on the map inside Tesla as is currently the case with Superchargers.

Most versatile choice, $1.50/foot + $70 once The Tesla wall connector is a 3rd generation charger and it includes Wi-Fi to allow software updates and remote service. Prices will reflect normality, not crazy COVID pricing (which seems to have about doubled cable prices). Since you didn't specify indoor or outdoor, I can't specify a cable or wire type (unless you run conduit). My understanding is this feature is active now. Unrelated: If you have any thoughts toward a second EV, brief yourself on Wall Connector Power Sharing, manual. You have 3-phase power (not likely outside NYC) AND want to power 2-3 Wall Connectors independently.Note this is mandatory if this is an outbuilding and there is already 240V power there, because you can't have 2 circuits or feeders of the same voltage to the same outbuilding. You want to feed a sub panel to power other loads there, which actually would be rather elegant I recommend it.There is no need for 3-wire+ground cable. The Gen 3 Wall connector's instructions are here. NEC 110.3(B) requires you follow the paper instructions which are UL-Listed as part of the device's UL listing.
Your distance is short enough that voltage drop won't matter.
