Thanks for the tips!I will check that it’s straight. The cage is rather narrow and perhaps later on I’ll look for a 9-10sp one and if it’s wider, a little less rub. I probably won’t make any other adjustments because it’s only a minor inconvenience. On today’s ride it only happened a handful of
I've never experienced a FD where I never had to trim, even with indexed
front shifting. After a while you'll get to know when you're about to have
chain rub and will start moving the fd a smidge before you up- or
down-shift the rear.

I agree, it seems likely that your FD is rotated just a wee bit. I'm not
familiar with "indexing" FDs, like your GRX 810, but I would expect them to
be wider than older friction only FDs, just to accommodate the fact that
indexing front shifters can't trim. Either I'm the best home mechanic, or
“…often making minor adjustments…” kind of goes along with friction
shifting, but if it seems excessive, check that the front derailleur cage
is absolutely parallel to the big chain ring. It only takes one chain jam
to knock it askew. Also that the outer stop of the front derailleur is
adjust
