A collapsed cave on land is a sinkhole. Is that not appropriate?

The natural=cliff idea is also sensible and correct for the edge of the hole

Natural=arch on a node is a great idea for the natural bridge between the
collapsed section and the open sea. There are plenty of similar features on
rocky coasts, Eg Oregon, Baja California, and in deserts due to wind
erosion (eg Natural Arches monument in Utah)

Small collapsed sea caves can become a “blowhole” if wave action causes
water to erupt up through the hole, but it doesn’t sound like this is the
case in this particular place.
