I thought the capacitor had something to do with power factors, phase angles, motor winding inductance, and all that magical AC stuff, which I never fully understood?

Watts per day, watts per hour is not meaningful.
Maybe you mean watt-hours?
For people more oriented around running loads from batteries rather than long genny runs, amp-hour at 12V are commonly used.
As an example for illustration
An efficient 12V fridge can use as little as 20AH per 24 hours. On freezer settings in hot weather, can get over 40AH per day.
That converts to 200-500 wH per day.
