When your inverter shuts down with the fridge it's simply telling you it can't carry that load. They're designed to do that, no harm done. As you have propane for the fridge I wouldn't upsize for that reason. IMO a smaller inverter will help protect your batteries by limiting the load you can put on them.
I have several solar lights just for decoration, to light up the flag, etc; but I STILL run the legal lights appropriate for the circumstances.
A row of solar lights around the upper decks would probably aid in keeping J. W. Redneck (and his boat) out of your bedroom, but don't mount them forward where they'd interfere with YOUR vision.
You'll note though that most solar lights don't last the night, so relying on them is not a good idea.
If I'm in a high traffic area I'll leave the 12v "porch lights" on all night, and also a light on each side to illuminate the side of the boat. I have enough battery capacity that they're not a concern.
