Just enclosed my back porch, would it be better to do spray foam insulation, fiberglass or a mix of both?

I have a 12 x25 room that I just enclosed from a Florida roomPlan on having 2 ceiling fans, 10ish outlets and a dedicated tv outletWhat would be the best way to even out the loadWould it be better to have the fans separate from the outlets, then divide outlets in half as well, so 5 outlets per circuit? Plan on using a 20 amp breakerJust trying to get a idea of how to plan wire placement and how much to getPlan on using 12/2
