I'm wondering if I should be doing anything special around
the wire and/or the electrical box when doing this.

Just don't let the wires be insulated by the pink board. Wire temps are
derated at ambient room temps. Insulation will collect/keep the heat in.

I didn't think you needed to derate cables in residential construction
unless you have bundles of cable. Around here, you are encouraged to
insulate as much as possible...no issues with insulating against
modern electrical cable. The exception would be if you had old-style
wiring (the type where the sheathing was prone to flake off over
time).
