You’re seeing recommendations of certain gauges here without receiving an explanation for why.
Ask your electrician to calculate the Vd (voltage drop) of your circuit with various gauges and you can choose the price point that works best for you (or DIY). Lower Vd at the outlet means higher power stability to your equipment. For example, running 10AWG wire for 100ft, while better than 12AWG for 100ft, may still not offer enough Vd coverage to enable your equipment to perform at its peak under load because the voltage is sagging so much.
Also use same gauge grounding back; some lower gauge wires run a 12 gauge ground (green) line back, so you may want to press for a 3 conductor wire (which incidentally has a 4th conductor for ground).
Vd is the primary concern for that homerun.
