I am trying to pick a wire gauge for wiring up a SUT. Is there a benefit to smaller gauge wire say 24 or 22 AWG vs the 20 gauge I have in stock?
Assume that I don't have a problem with purchasing a few feet of whatever gauge is appropriate.

I suppose you have the resistance of the pickup and set the lower cutoff frequency. From these values you can calculate the primary inductance. With a given core this determines the number of turns. You can wind up 100 turns and measure the inductance, then you can calculate the required number of turns. Now the goal is to fill the available space with the highest wire gauge, in order to minimize any losses in the coil. Also the gauge ratio between primary:secondary should be inverse of the turns ratio. Higher number of turns = smaller gauge. I think a primary of 30 AWG and secondary 38 AWG is more realistic for a small laminated core.
I'm looking for gauge recommendations for the hookup wire. I am not trying to wind my own coils but thanks.
IMO hook up diameter of wiring from SUT to PCB or RCA input/output not so important, than its material.
The later is depends of internal wiring of SUT (copper/silver) and interconnect type between turntable arm and SUT or SUT and phono.

Use whatever you have to hand, that is easy to work with. Sometimes, solid core is best, and other times, stranded very flexible stuff is easier. I think that sort of workability is more important than the gauge, and maybe more than the material its made of. If you need it shielded, then maybe that limits your options.
