Ideally, I am looking for two planes that are simulated really well and really deep (study level)

1. a small plane to begin with
2. An airliner.

But I would already be happy if there is at least one "neraly" study level plane included in the Standard Edition of the game or available for a small price.
In MSFS I was flying the Cessna 172 Skyhawk (G1000) and the FlybyWire A320nx, because they are two very common planes a pilot might fly in reality. I wouldn't mind flying them in MSFS 2024 but I am open for a change if that results in a better (meaning more realistic) simulation quality.

Most posts I can find on the topic of "study level" stuff are from 2024 when the game was released.
