Yea double wired sucks if anything takes down lines (or power in many cases) in the area... Starlink is great for that reason alone, and the back-up plan is only $10/mo which you still may be able to register for even if your area isn't eligible for full residential scale service

Perhaps a high gain 5G antenna you can put on the roof would make cellular at least serviceable for backup? If you can get a pole high enough for line of sight it could make a big difference... but that's probably going to cost just as much as Starlink equipment and cell towers are often impacted by power outages too.
