Surely the important thing is to get the car to a standstill as
safely as possible?

So just use the foot brake a bit harder than normal to bring both
car and engine to a safe and controlled standstill.

Some people talk or behave as though the foot brake is some incredibly
delicate system that will break if the pedal is pressed down hard.

The orginal start of this thread was based in the US. They mostly
drive automatics over there so the pigging thing will change down to
counter act the braking. Selecting N still doesn't strike me as
"right" though, selecting the highest fixed drive and braking ought
to work. Assuming the auto box and/or computers will allow that
change to happen with the engine under full throttle.

Given that the accelerator pedal now only operates a potentiometer and
autos don't bring mechanical connections to the driver, there is no easy
way of knowing what a "stuck throttle" fault is and how things are going
to respond to the driver's random fiddling. The foot brake is a known
quantity and the only system with sufficient independence.
