Specific questions about USB/WiFi interference

Main Question:
As best I can recall this became an issue with USB 3.0 and 2.4 GHz WiFi. What if a device attached to your computer’s USB 3 port is just a USB 2.0 device? Does that negate the potential for interference or is there something about the frequencies involved with the USB 3 controller and port themselves that might cause issues?

Related Questions:
Did anything change with what is now USB 3.1 Gen2 (10 Gbps)? Does the type of port actually factor in now for interference potential: Type-A vs. Type-C?

Reason:
I’m thinking about running an Intel NUC in a headless configuration with WiFi connectivity for access. The NUC would be a music file host attached to an external DAC via USB. I’m just wondering whether I need to get a 5 GHz WiFi dongle in order to avoid interference from the NUC/DAC USB connection. I’m reasonably certain that a majority of DACs with USB attachments are only USB 2 devices. Hence that piece of the puzzle.
