Soon to be sticking an 11-40T cassette on a GRX 2 x 11 drivetrain. Up from 34T (technically outside Shimano's suggested range) Will be using a goat link.

Is it best practice to up the chain length when increasing cassette size?

Almost certainly with that kind of a jump, yeah

I use 11-40 2x GRX, no need for goats but always size the chain properly, so big to big plus one full link in this case, you're better off with a new chain on a new cassette anyway.
