Hi and welcome to the world of DCS.
FC3 is a good option but you won't get a clickable cockpit. The flight models on most planes in FC3 are really good though.
If you want a good flight model and a clickable cockpit without getting overrun by a hundred million actions and buttons i think the safest would to be start with either one of the WW2 planes P51,109 or 190) jet era F86 or MiG15.
Personally i think the MiG-15BiS would be the best option.
