My thinking r.e. the reach screw is the same.
Am with you on the noise issue too, its definitely worse on the front. The combination of these issues has lead me to be very much on the fence regarding disc brakes on road bikes. I'm not sold.

Replace it with R7020, job done.

I have had the grub screw problem, but in my case it was only part of the issue. If your levers also have fore-aft play then the piston in the master cylinder needs replacing. Once I did that they've been great.
Oh and all disc brakes squeal in the wet.

In the same boat with Rival 1, I'm not sure if the reach screw is slowly unwinding - otherwise am out of ideas.
On the noise, I found that checking alignment and following a bedding in procedure helped a little but the front is nearly always bad when wet - likely related to contaminants off the road. The front brake gets hosed in crap, possibly from the mudguards.
