However, most audio interfaces in modern devices use USB-C. And Bluetooth is more secure than connecting stuff to your USB-C plug :)

Why you think that Bluetooth is more secure than USB-C? To me Bluetooth seems to be pretty vulnerable legacy.
It depends on what you want to do. Bluetooth 5 leaks a random number that people can use to track you.
USB-C connection, in the other hand, can take full control of your device if you are not careful.
