Caveat: Low hours pilot, coastal area, fixed gear. Those initial photos mostly look survivable? Depending on where you are, the surf conditions could also be a factor. Ditch in a rough sea and you have a whole new problem set even if you exit before sinking, plenty of people drown in rough surf / strong currents without already having been knocked about in a plane crash. My plan: option 1 is on the beach, with the harder sand just above current tide mark as a "nice to have", failing that (people, rocks) option 2 is calm waters close inshore, failing that (breakers) then ditch further out, jam something in the door/canopy and pray.
