I am looking for advice on the correct grade / type / manufacturer of
1/2 sheet abrasive to use with my sander to do things like smooth filler
after filling in holes when I have moved sockets, or preparing a wall
for emulsioning after removing wallpaper? I always seem to end up with
the paper clogged with paint and filler long before it is smooth.
Perhaps I am using too fine a grade (120)? What about the different
types, silicon carbide, aluminium oxide, etc?

Filler is great for clogging paper, whatever grade you use. Using a
perforated sheet with an extractor helps. I tend to use 80 for coarse,
then either 120 or 180 for finishing (sometimes 240 for really smooth).
