Music/Audio Autoplay with CarPlay & Bluetooth
The fact that this continues to be an issue after all these years really goes a long way in showing just how much Apple listens to customer complaints.

iPhone 11 Pro
I have two cars one with Sony DSX A410BT and the second one with Sony MEX BT3153U
My iPhone 6 iOS 12.2 when connects to this audio system
As soon as the ignition is put ON in the car with the audio system, Sony DSX A410BT connects automatically to Bluetooth and then automatically opens iTunes and automatically starts to play from where it last left off.
All Automatic: Bluetooth connection, Opening iTunes, Song selection, Play
But, But - Same iPhone
As soon as the ignition is put ON in the car with the audio system, Sony MEX BT3153U does nothing automatically
Manual Connection: Connect Manually to Bluetooth, Manually Open iTunes, Manually Select Songs, Manually Play
How to use CarPlay with your iPhone - Apple Support
Mine acts like the first one in your list. When I start my truck, my iPhone automatically connects via Bluetooth and starts playing whatever I was listening to last or, if I happened to be reading a news story with related audio earlier in the day, it will play that. I tried removing the Bluetooth connect entirely, figuring I'd just use CarPlay all the time, but as soon as I plug my phone it, it does the same thing. We really need a way to disable auto play.
I set up some shortcut automations that will pause Now Playing when connecting to CarPlay or my truck bluetooth, but haven't had a chance to test it yet. Perhaps that will do the trick.
