Nice first post - welcome
The one thing I would disagree there is that the switchology also becomes a big part of fighting - especially in say the P-51 where it not only has a throttle, but prop speed, and if you want to change something you have to look down into the cockpit to find it and click on it (as you would in reality ) in the middle of the fight.
Even with a HOTAS in an F-16 there is a lot to think about in the fight - so although its a major PITA learning what everything does I find that gives you more realism for having to do functions the real pilot would - and once you get to know things they often give you more flexibility.
Sims like SF2 are great because they get you into the fight with minimal training - you still need to invest time practicing dive bombing and dog-fighting - but doing this is a lot more fun than reading up about the EGI etc
FC3 with its 6DOF pits, 3D models and AFMs looks to be a perfect compromise and a Jet handling the way it should is a great thing - but with that quality comes massive amounts of time to create them.
