In the log homes we have done, we cut in receptacles in the large baseboard, positioning them so they fall in the inset between the first and second logs. then we jsut staple the NM to the logs, and let the trim guys cover it with the baseboard. The switches are mounted into the large area around the doors (for shrinkage in the logs) that gets covered with a wide plank.
Most of it is fairly normal NM wiring, with most of the prior planning going into lighting layout, and getting switch legs in place before the roof system/second floor is set in place.
I've never done a slab log home. THAT would be a bear.
