Honestly the thing that mattered most for me was getting a home L2 charger sorted. Plugging in overnight and waking up to a full car beats the gas station every time, and you stop thinking about it after a week.
The 80% thing only really matters if you're going to be charging at home anyway. Daily use, 80% is fine. Road trip, charge to whatever gets you there. Nobody warned me that I'd actually come to like the forced breaks on long drives, though. Took 3-4 trips before it clicked.
