THE SHORT ANSWER
Here's the approach.
AI Audio Assistant is available in Resolve Studio 20. It can categorize tracks, balance dialogue, duck music and add processing for the chosen delivery target. Put different types of sound on separate tracks before running it.
Treat the automatic mix as a starting point. Blackmagic explicitly recommends playing it back and making further changes or undoing it if needed. A track assigned to the wrong category can be corrected from the track header context menu.
