I would go for option 1. Make sure your transport is pre-arranged from the dock. Get off the ship early to ensure you make it to the cave by 9. It's well worth it. If you can, get the driver to drive you to the beach afterwards. The dock isn't too far from the boatyard but allow at least 30-45 minutes to get back. Based on your preferences and the other activities in other ports, i would definitely do option 1

It depends on what type of water you want. Carlisle bay is flat. Some days almost like glass. gentle waves, gradual deepening. very serene. There should be ample rentals of chairs / umbrellas but the sand is so nice, a towel will suffice.

Accra/Rockly is a bit more lively water wise. There are some waves you can bodysurf on and some calmer parts as well. if you go out far enough, there is a small reef with fish and such. the water depth prior to the reef doesn't exceed 7.5 feet. gradual slope as well. Lots of rentals here.

Both locations are about close to the dock. 10 mins for Carlisle and 15 minutes for Accra. My personal fave is Accra. There is a Chefette chicken place across the street, local drinks and fish cakes on the beach.

Taxi's are plentiful at both locations. Have fun!
