1. Is there a way to cut off the grid after a certain amount, so that it
doesn't show the blank gap at the bottom? Or alternatively, cut off the
grid after the cave ends? Or "show the next grid line if the cave is
within 5 metres of it“?

Anyway you may add blank PDF or png to your map to cover part of grid:
