The only other option I can think of for sanding right to an edge
that can also achieve a good finish, is a linear action sander. These
aree far less common than orbital or RoS machines. Festool do one:

For hand sanding near an edge I find the wet/dry paper bonded to a
fairly firm sponge works well. Being wet/dry if it clogs with plaster
dust it can be rinsed out for reuse.

one wide side plus one narrow side is one grade of paper while the other
two side are a different grade of paper.

My old permeagrit is essentially that. I am going to use my newer one
because the old one is 'plumb wore out' - which shows how much its been
used as both wood ceramic and metal file..

I think having recieved all the good advice, that that is as good as it
will get for the 'irreducible residue' of sanding...
