Bravia 7, Sony HT-G700 sound bar, Apple TV 4K

Just upgraded from 10 year old Samsung to Bravia 7. At first I was getting audio drops while watching Apple TV+ (Netflix, Disney had no audio loss). I changed connections with Apple TV going through the soundbar and soundbar into Arc-e on Bravia. That has worked.

I don't understand how to select the right settings when it comes to Dolby Vision and HDR. In Bravia setup process there is External inputs and HDMI signal format/VRR. What Do I set each HDMI signal format for HDMI 3ARC/ARC ( now on Standard format) and the HDMI 4 (PS5) now on Enhnanced format (Advanced) what do these mean?

Should I use VRR (Variable Refresh Rate) I do find the screen studders a bit and which format to pick? standard, enhanced or advanced? Thing is I also have settings on Apple TV for all that.
