Battery went dead overnight, won’t even try to turn over. Battery seems to be holding a charge now. Help me! What should I try. It was so dead that the AV had to reset. Barely even a light.

How old is the battery? Was it super cold overnight? How old is the rig? (Helps if you put that and whether LC or LX in your signature on here.)

One additional oddity. I am charging it but the car seems to think it’s “running”. Lights are staying on the dash etc - seems like the car should not have any dash lights unless I open the door.
When voltage isn't correct these vehicles do very odd things.

Charging the battery a the store and got under the car to tap the solenoid. My theory is that I way wiping down the dash and hit the start button without the key fob present and it stayed in that position all night. Couldn’t get the battery past 12.3 and that m.

Just replace battery, simplest fix unless problem continues.
Not sure what type of charger you're using, but most all will get it to full at 12.6 - 12.8V. At full charge after rest, if it's falling to 12.3V, the battery health is in question. Doing a test with a simple hydrometer, would probably show several weak cells, which is why it's not reaching full voltage.
Most batteries are considered end of life when they reach 80% of original capacity. Combined with winter cold, and a deep draw incident, the battery could be done.
I'd take @RET2's suggestion and just replace the battery to eliminate that as the problem. Battery problems usually show up this time of year when the weather gets cold. They're cheap and a maintenance item anyways.
