I haven't done a lot of cable shopping because I've ended up with a huge accumulation of them over the years, including some of those pesky charge-only cables.
Generally, if you can use the cable for data on another device then it should be fine for use with an Arduino board. There might be some rare cases in which a cable is damaged in a manner that causes it to still get electrical connections on one device but not on another, but that would be a very rare occurrence.
I see them appear under System Preferences → Network, but that doesn't matter here. That's if you want to connect using a modem, and even then you don't need it. (Use the "screen" application from the command line.) You should see the devices in /dev if you view from the command line.

But if you are seeing the Nano Every there, maybe there is something wrong with you Arduino IDE installation.
