While, as you said, both wires will conduct electricity just fine, they will have different AC impedance.
I would guess this wouldn’t make much of a difference if you go Audio->Ethernet->Audio, since sound is at fairly low frequencies. But Ethernet->Audio->Ethernet might have problems with really high data rates, like GiB/s.

I’ve done this. I’ve made speaker wire to ethernet adaptors to connect speakers in a different room through the walls to an amp. Feels and probably is so wrong.

It really depends how much power you put through the cable, ethernet is something like 0.2 mm2 per core. You’d definitely want to double up cores.
