Guys, IMO is tough to give quick answers to complicated topics. To discuss induced noise one can only qualify a transmission system which includes the driving source and topology, the cable and the receiving source and topology and the common mode noise between send & receive. But generally, cables with twisted pairs or quads signal conductors have better immunity to magnetic fields than single signal conductors and overall shield(s) add immunity to E fields when paired with the proper electronics at each end. As in ElectroMagneticInterference.I'll take tips from whomever I can get them.
I learned of coax noise immunity in school when I got my BSEE. The 'dig safe' guy was commenting on where cables might be buried... not their noise immunity. Like I implied above, I'd avoid routing data with power.

IMO Running signal / control cables together with AC power supply cables is not a good idea for multiple reasons. Last I checked the US NEC code dis-allows this generally.
I repeat, not a simple topic, my go to reference; Grounding and Shielding: Circuits and Interference by Ralph Morrison, a mere 224 pages.
