... I'm sanding down the edges of my stairs as we want a runner carpet
rather than edge-to-edge. Want natural wood at the edges of the
carpets but there are a few gaps to fill.

Any recommendations for flexible wood fillers that can take that that
sort of movement and will also take a stain?

Retain the sandings. Mix stiffly with pva or similar. Use result as filler.

when I did that recently the "filler" dried and ultimately sanded to a
*lot* darker colour than the wood....bugger!

OP:- Could you just use decorators caulk on the horiz/vertical joins
you mention (step to stringer) assuming stringers to be painted.
