The reason for radiators under windows is that you get a cold
downward
draft from the window which even in a well heated room makes your
feet
feel cold and you perceive that the room is much colder than it
actually. Putting a radiator under the window counteracts this
downward
cold draft.

I think that's much less important with double glazing and better wall
insulation as there won't be such a temperature gradient across the
room.

It's not so much a temperature gradient across the room as air
ciculation. The windows, double or single glazed, will cool the air
this becomes more dense and sinks drawing warmer air down. This sets
up a circulation, the bottomm line being your feet are in a cold
draft.

Decent curtains outside the window reveal and tucked behind the top
of the radiator keep the warm air in and any circulation within the
reveal. Even better if you can fit another set of curtains adjacent
to the windows.

Behind doors strikes me as a really bad place for a radiator.
Are doors habitually left open or closed? Open is going to restrict
how much heat the raditor can effectively transfer to the room.

Will there be enough space for a radiator to fit without fouling the
door when it is open?.

Doors tend to be opposite windows, this will enhance the circulation
due to the window cooling effect.
