My electrical service entrance is on the opposite side of the house from the municipal water supply's copper pipe, so the panel ground wire runs about 30-40 feet through the house before it's bonded to the city copper.

Is there any problem running a 12-2 wire (120V + neutral, panel is 240V split) along the same path as the panel ground (same stud/joist holes, staples, etc.)? Would inductance from the circuit cause any problems with GFCI receptacles in the house?

It should not. The magnetic fields of the hot and neutral conductors should cancel each other out, as explained in this answer.
