Prefer BT only really means it will use the phone connection to the car stereo instead of bluetooth streaming. Prefer BT also means it will accept voice commands via BT headset/car connection.
With Speaker and prefer BT off, if your phone is paired with a streaming device, Waze will still use it. Not sure if that's because of the OS, hardware or Waze, but that's the way it works. Waze hasn't implemented, on iOS for example, the standard audio output selection mode that every other app in the world uses...
