Wiring small cottage. Wish to have benefit of an Arc Fault Circuit Breaker for the wiring on the way to the GFCI protected bathroom from the panel. Is that advisable, effective and safe?

Thinking that the hazards that an Arc Fault Interruptor guards against (over heating wires, nails from wall finishing installation-drywall, knotty pine board nails) contacting the wires inadvertantly, would not be protected by a GFCI receptacle further down the circuit from the panel and wiring travelling to the bathroom.

I know code does not require this, but wondering if this would a bit more safety insurance. Please advise. Thanks.
