14 gauge wire off of 12 gauge wire
Is it okay to transfer from 12 gauge wire to 14 gauge wire in a junction box if the 12 gauge wire is run off of 15 amp circuit? My understanding is that the 14 gauge wire can handle the full load a 15 amp breaker can put on it so switching from 12 to 14 should have no impact.

Yes. As long as the overcurrent device (fuse or circuit breaker) is sized to the smallest wire, in your case #14 wire/15 amp) it is fine to use a larger sized wire in the circuit.
