Not sure I agree that FedEx is easy to drop trips when outside of Nov and DEC. Staffing has been tight, deliberately so, as long as Ive been here and even when it appears they have slack to let you drop, it's often refused. I don't think anyone could, on a regular basis, drop below min guanentee (66hrs) without CP approval, and than I'd expect a lecture on why you're here if you don't wish to fly. I'd look elsewhere for part time employment.
Regarding schs, from a middle seniority WB capts point of view, FedEx has possibly the greatest diversity of flying of schedules of any major airline flying, certainly on the MD-11/MD-10. Domestic or international, take your pick, good and bad in each. The bad are the hours, domestic, mostly nights, unless your senior, intl, night and days, longer layovers (good, more rest) but the time zone changes can pay havoc with sleep cycles and often have a negative affect upon (trying) to readjust when returning home.
As far as family time, if you live in domicile, QOL can be very good, especially if you bid reserve and are lucky enough not to get used much. If you live out of town other issues come into play, ie; bidding layovers in the city you live. Can be a GREAT DEAL, but at the cost of scheduling flexibility, equipment/seat choice and seat progression (remaining senior to hold particular lines) and diversity of your flying experience (same old flying from your home to hub month after month). Some guys like that or accept it as the price they pay to be home more, others find it to constraining/boring and do other things. If you intend to fly INTL and not live in domicile, you will be away from home, 2days mins (MEM to STN or VCP and return) up to 2 weeks (around the world). Still the same time off (more or less).
