Type E and F plugs are not really a thing anymore, today it's more common to find combined Type E/F plugs.
Fuses in british plugs are a mistake and only a requirement because of sketchy practices allowed in british electrical code immediately after WW2. Nobody else does that because nowhere else electric code is built in such a way that it is necessary. Switch seems to be mildly useful tho
C/E/F also have shutters, probably more types do that too
