I mean this as a general reply, but I am not sure where it will end up in this thread, so I apologize.
There is a lot to address here. The dealer should have sent you out with an 80-100% charge and instructions.
The Tesla charging system is much better than the others in terms of numbers. There are a large number of them in many areas and each site usually has at least 8 chargers. We bought our Model 3 in 2019 and mostly charge at home but often are on the road with 160-200 mile trips and have been to many Superchargers. I think in all that time I have encountered maybe 3 individual chargers (not sites) that were out of order. I have never had to wait at a site.
Charging from 20% to 80% (the recommended usual maximum) takes 20 to 40 minutes, usually, during which I can stretch my legs, use the facilities, take a nap, etc.
Charging is simple: pull up, pick up the cable, press the button on it and the car port opens and plug it it. Removing it is the reverse. Billing is done through your card on file so there is no transaction stuff at the charger. And of course, you do not have to stand there holding the cable! And you can do it in the rain.
If you select a charger on the map, the car will precondition the battery for more efficient (faster) charging). You can see a map at the Tesla website.
It didn’t occur to me early in ownership, but you do not have to do a full charge at every stop; if you are only going another 60 or 100 miles to your next charger, you don’t have to have a full charge.
The Tesla connector is becoming the standard so it will be easier for non-Teslas to charge. Several years ago, Musk said he does not look at the Chargers as a revenue source, but he may have changed his mind and may even being charging non-Teslas more. The Tesla chargers are cheaper by a lot than the others.
I have a Tesla 240 volt charger at home, but for the first three months I charged it from a 120 V outlet and sometimes at Superchargers.
As someone mentioned above, range anxiety disappears pretty quickly.
I’m not sure what the snowstorm anxiety is about. I have been in my parked car for 10 hours, including sleeping, with outside temps dipping to 11 degrees using the heat as needed with a winter coat and a thin down blanket with the charge dropping only from 80 to 70%. And I had no worries about noise or carbon monoxide.
Maintenance-I’ve needed tires, I changed the in-cabin air filter and I use washer fluid.
If I have missed something, let me know.
