It doesn’t matter, USB-C won’t use a voltage that’s in excess of the voltage the receiving device can accept, so even if the cable is theoretically capable of a higher voltage it won’t matter. Just like you can’t overcharge your phone battery anymore, the charging will just stop automatically at 100%.
The switch cable won’t carry data which is odd, but it won’t break your phone and you probably don’t need data most of the time anyway.
