Why use an FCU if there's a conventional plug? Wouldn't a simple 20 amp DP
switch be neater and less confusing?

Yes, it would - better all round, saving the hassle of the "wrong" fuse
blowing. Only justifications for an FCU would be if you were feeding
multiple socket locations, or "can't find a 20A DP sw in old-georgian
scroll-effect brass, but can get an FCU in same this rainy Sunday" (or
whatever weirdo decorative demand has been laid down by the domestic
authorities ;-).

But you're quite right, the 20A DP switch wins in practically all respects.
