I'm about to start cutting some cable chases in a wall that's going to
be painted, but when I last did this (a long time ago) I never managed
to fill the chase so it disappeared completely.

What I've found works well is to fill it roughly (using the One Strike
filler mentioned in the ceiling thread) and then after that's dried I
"pack" it in with finger pressure, and re-fill the shallow dip with
screwfix plaster filler (in a frame gun cartridge) which I find gives a
very fine/hard/crisp finish.

This house is all lime plaster

Dunno whether the plaster filler would blend in, or stick out, from a
lime finish ...
