Unless it’s -10°F. Then your miles don’t compute at all. Charging speeds should be talked about in KWH. What miles you get depends on too many factors.
Moving the goal posts....that wasn't the question.
With 13 hours to charge and only 50-60 miles a day, you could actually get away with level 1 charging, weather dependent. You’d slowly lose SOC over the week and be able to top off on the weekends. So for you, I’d say the deciding factor should be more about cost, rather than time to charge. A 40 amp EVSE will charge 25-30% faster than a 32 amp. But it sounds like you don’t need either of those really.
All highway, or a mix of city and highway? The speed you drive impacts range significantly, but even then you can easily add enough charge with the 32 Amp charger to cover your daily commute. If you start to get behind, you can catch up on the weekend.
Then 32A will be plenty. I personally like the flexibility of having a plug-in charger (EVSE) so that I can switch to the included Ford mobile charger if the EVSE craps out for some reason. It probably won't change the cost of the unit that much, but there is certainly no reason to buy the much more expensive 48A EVSEs that have to be hardwired. I have a 40A EVSE configured for 32A.
Do you have time of use electric cost differentials? In many areas it is cheaper to charge during certain times of the day - normally middle of the night. You may want to take that into consideration. If so a higher capacity charger may be preferred to charge in a narrower charge window.
