If you're running pre-wired cabling (Romex, BX, etc.) use 4-wire cabling. The difficult question to answer is what gauge wire to pull? At a minimum, in a workshop, you should be running #12 (gauge) wire. But you may need #10 (typically 30 amp loads) or larger, depending on the load. So it's always good to configure your anticipated machinery and load demands before wiring your shop, and plan for the future when doing so.
Julie are you an electrician? Nice to have someone else on here that knows the NEC.
