Looking on the screwfix site they have 'open' and 'closed' 20mm PVC
grommets - the images look identical, so what's the difference and is
there an advantage in using one type over the other?

The other name for closed is 'blind'. It is a disk rather than a ring, as
it were. You simply fold it in half and use sidecutters to make a slit
while not cutting into the 'ring' part.

Since you'll be making good afterwards, either type will do.
