I am sure that Seafires were used for at least one carrier deployment in Korea a few years later.
The book by Guy Robbins has chapters on Royal Navy aircraft 1918-1339 and aircraft 1939-1945. Apart from the lack of naval control, Britain, unlike the United States or Japan, expected to be subject to air attacks against the home based so the priority was to design and build fighters to defend the UK. Everything else came second.
attrition rate for the Seafire in things like landing accidents was atrocious, >50%, it was right to the end an aweful shipboard aircraft. Your chance of being killed by enemy action was much lower than in a landing accident. It was used by the FAA after the war because it had to, not because they wanted too.
in all respects the Hellcat and Corsair were better aircraft sorely missed by their pilots.
and after the Avenger, going back to the aweful, and simply dangerous Barracuda was moving back a generation.
the Hawker Sea Fury proved to be an excellent naval fighter, but not anything much over the F4U-4 model Corsair the FAA was about to receive at wars end.
