BT and wifi for CM4 - dongle?

Dear friends, new to this place, so hi! Bought a CM4 w/o wireless capabilities a while ago for learning/tinkering (linux, not hardware). Will now move the learning/tinkering to a desktop PC which frees up the CM4 for other purposes. Goal: Turn a wires-only CM4 into a headless and wireless media player that can connect to bluetooth devices. Question: Does anyone have experience with wifi-BT-dongles on a CM4? Alternatives, pitfalls? Thanks!
