You could argue for the F8F-1 (deployed in combat squadrons, but didn't actually see combat), but the other two don't even come close.
The first production Sea Fury didn't fly until September 7, 1946. Likewise, the La-9 is purely post war. The prototype first flew on June 16, 1946 and production planes began delivery in February of 1947.
