I like number 3 but the old "junction boxes must be accessible" argument

(not by me) with junction boxes under floorboards, underlay and carpet.

So how "legal" is my option 3 ?

Under a floor still counts as accessable... plastered into a wall does
not ;-)

You could even use two JBs is you want to make the new socket part of
the ring rather than a spur.
