It is obvious you have done a lot of reading and research about bee keeping. Nothing wrong with that, but, nothing is more learning than actually opening the hive and getting to know and handle the bees and interpret what you see.
You may not intend to harvest any honey but you need to make sure the hive has ample room, not honey bound. With too much honey and no open cells the queen has no place to lay eggs and will swarm. If the hive swarms too late in the summer then they may not raise a queen, mating etc, in time to recover for the winter. Supers need to be added if honey bound. Also, in time a second hive will allow you to swap resources from one to another if necessary.
Grand Isle has a reputation for not having any bears, so, maybe an electric fence is not needed. Time will tell.
Mite treatment, that is a whole lot of options and advice. Practically every beekeeper has different ideas and methods for treating for mites. Some work some of the time, some none of the time. A lot depends on the method and the time it is used. Learning the breeding habits of the Mites is important to decide what method of mite control is used. A never ending battle.
I know you are concerned about covid but even if you could get a local mentor for a "distance" visit the first time or two opening the hive would be extremely helpful. Or if you could visit a local beekeeper to observe how it os "done".
There are a lot of Utube videos available to view. A great series of videos are from the University of Guelph, in Ontario. Check them out if you get a chance.
Although you may want to someday shed a vail etc., most hives vary in temperament and are not always docile. Heat, humidity, harassment by an animal, skunk, raccoon, may effect the temperament. I can most of the time view my hives from a short distance, just to look, with no problem. BUT, once in a while a guard bee, from maybe 40 feet away decides she does not like me and buzz around, bump, and sometimes stings, for no apparent reason.
Always wear a vail and have a smoker lit and ready.
Once again, good luck with your beekeeping journey, "may the force be with you" !!!!
