Well, it depends on what you have in your community folder, or linked in with the addon linker.
PSXT will pick up every converted AI model or 3rd party plane you have in this folder. The more you have, the more it can display. (I have every AIG model available by the way) Just have a look at my screenshots. They were taken at EDFM (Mannheim) a small regional Airport near Frankfurt and just around the corner, at EDFV (Worms) my lovely homebase, an even smaller private/hobby pilot airfield.

You see…plenty of GA traffic in real time. Maybe not with the exact liveries or tail numbers but the planes are there.
How much live traffic you get depends on time of day, weather and the location itself.
Just use the learner tool for a few hours during day time. It works really well.
As I write down this comment, I have FlightRadar 24 open on a cheap tablet and the sim running on my main monitor and I see Diamond 44’s and C172’s doing touch & go’s at EDFV like they did in real life.
This is awesome. I feel like in simmers heaven
