Wire sizing is identical. NEC Table 310.16 ampacity values have not changed since NEC 2017. Whether you are wiring in North Carolina or Virginia, a 20A circuit uses 12 AWG copper and a 30A circuit uses 10 AWG copper. The differences between states are in code enforcement, not in the wire sizing itself.

GFCI requirement differences
