OP, I think what I'm hearing is the 40kWh Leaf might
work, especially with an en-route QC, absolutely requiring a QC along en-route with battery degradation or in cold weather but you'd really be better off with the Leaf Plus(which I believe you are looking at). That said even a Leaf Plus won't make it there and back(288 miles) without charging of some sort, probably not L1 but at least L2(home 240v) or L3(away QC station) would also be OK. Assuming you can get a decent 240v plug(or EVSE) wired at your cabin and you're there for at least one overnight you should have no problem for years to come with a Plus not have to worry about charging en-route.
You might also want to think of a 240v L2 plug(or wired) EVSE at home although with your limited home driving you might be able to get by with L1(120v) and basically leaving your car plugged in all the time while at home. In your case since I believe all Plus's come with a L2 EVSE then just having the correct 14-50 plug at home and cabin would be your cheapest alternative(although personally I prefer to leave my car EVSE in the car for emergencies and not have to bother winding it up and stowing it every time I charge, the call is yours).
IMO it sounds like a Leaf Plus would be an ideal vehicle for you to avoid gas stations for many years to come and enjoy driving a nice clean quiet EV
