With regard to the settings which were added/expanded with SU3, they should follow the same basic philosophy we have recommended previously. Essentially, the fewer other objects the simulator is generating, the more
I don't believe there is anything mandatory that we would recommend setting with the new SU3 options, and the settings can largely be set per each user's personal preferences. However, we do recommend that the "Parked Aircraft Quantity" is set to OFF, as that will prevent any MSFS default Ai aircraft from generating at gates and taking parking spaces away from FS Traffic aircraft.
I have attached a screenshot of how I have those new settings set on my PC for reference:

Hope that helps.
