Yes, and the cage should be nowhere near touching anything.

Yes!! thank you, I will compare to my set up later today.
To be clear, the cage rubbing against the cog happens when shifting from the third largest cog on to the penultimate cog. Looks like your derailleur cage has some rub marks from the cassette?

Either way, I'm starting to believe that my derailleur might be bent. I can't see any other reason why it would shift OK with a 9-36 cassette and not with a 9-42.
(Hanger is straight, shifting problems are replicated when installing the 9-42 cassette on "road wheels").

Not exactly, 3mm is considered the maximum distance. That is checked when the RD is positioned on the 12th Cog, and space between upper pulley wheel and 13th cog.

When doing installs. I normally use 3mm as the starting point and adjust the b screw position until shifting is smooth and quiet. Sometimes, that means the spacing being more than 3mm, and others even closer.
