First order of business:
Your well pump: Is it a 240v well pump, and does your inverter have a split-phase output that will accommodate the pump and the balance of your “stuff”
Under normal use, the well pump will be used very infrequently.
Go LED for the lights - that, and the box fan will be your biggest draws per 24 hour cycle.
A small fridge can be very efficient. My big fridge draws an average of 65 watts over a 24hour cycle.
Also, manage your drawdown of the AGM. Keep it above 50% charge as a matter of routine. It will last longer. If you need the full capacity, get another one and tie them together in parallel.
