macOS sends your audio to whatever connected last: AirPods waking up in a bag, a monitor waking from sleep, a headset grabbing your mic mid-call. Tunestack lets you rank your output and input devices once, and always uses the highest one that is actually connected. Pick a device by hand and it steps aside. Profiles for different desks. No permissions needed to switch devices, no network access, no account. $8.99 once on the Mac App Store.
