12 guage wire israted for 20 amps and 10 guage is rated for thirty amps!
12 gauge is what is required, as it is rated for 20 amps. 10 gauge is rated for 30 and will be more then enough. Oversizing wire in your case isn't necessary. The thicker 10 gauge wire is harder to work with and will more then likely cost more.
Yes, a 20 amp circuit requires a number 12 gauge wire.
yes
In residential wiring applications the most used is 14 gauge wire for light switches as long as the circuit breaker or the fuse is 15A. If your lighting circuit is on a 20A fuse/circuit breaker then you need to use 12 gauge wire
NEC states that all GFCI's require a 20 amp circuit, the wire size for a 20 amp circuit is 12 gauge.
A 20 amp circuit with #12 gauge wire will work in any event but if the nameplate recommends a 15 amp circuit then #14 gauge wire on a 15 amp circuit is sufficient. In either case you will have a double pole breaker and your equipment may not require a neutral. Always run a grounding conductor.
A wire gauge is a number that indicates how thick the wire is. A larger gauge number means a thinner wire. Gauge and diameter can be linked by looking up wire tables.

Use 8 gauge wire.
Use AWG # 6 wire.
No, you can never mix wire sizes in a circuit.
Yes, the smaller gauge number, the larger the wire is.
14 AWG.
