My my take on shielded Cat 7 and. XLR for ground issues is to go with standardized configuration and look for the real cause of any grounding issues. I must be blessed because between my quality XLR and Cat7 cables I’m totally silent and very musical. I didn’t create a problem before it existed. My only grounding issue occurred with very old tube gear that I was toying with. The problem was amp related not cable.
Shielded LAN patch cables are so cheap it’s not worth thinking about. Just buy shielded.
