“1. Be able to power critical items such as refrigerator, freezer, lights, television and radios, and at least one good sized room type air conditioner.”
You may want to look into propane or kerosene refers/freezers, as they can run on next to nothing, and have to require you to fire up a generator for that capability.
For running fridges & freezers, remember, they don’t have to be constantly run, just run down to temp, then keep your freezer covered with blankets.
So, for short term runs, an inverter hooked up to your car (leave it idling) will work great.
