I'm having great difficulty in finding anywhere that sells bog standard

in order to get a knob? Can anyone advise?

You'll probably have to make/modify one.
As many are imported, they are all different nowadays.
You will be lucky to find an identical valve to the one you've got
even to buy the whole thing.

I pretty sure that an 'ordinary' radiator valve is (or used to be)
pretty well standard, with a 1/4" square spindle. I think that most
'ordinary' knobs will fit.

The square ones are rare, most have a rectangular fitting maybe 2mm x 6mm?

Yes, you may be right (presumably like this one).

I'd assumed that 1/4" was the standard.

Also, I'm beginning to wonder if 'cap' is the correct name for what
ordinary mortals would call a 'knob'. I would have thought that a cap
went at the other end of the radiator from the end where the knob was -
but I see that some so-called 'caps' appear to be meant to be turned
(and not just cover the end of the spindle). What is correct?

The valve with the cap is a lockshield valve intended to balance the
system only not for general use.
