Any plane is fine. You can decide as you go, what level of detail you're willing to strive for. A highly accurate Warrior can be just as difficult to model as an A380. The trick though, is to have a passion for the plane, because by the time you're done with it, you'll feel like you're married to it :)
The P38 tutorial is good for getting a feel for it.. there are dozens of others. The process is literally so multi-sided, I'd say that actual modeling is less than half. Animating is a handful, and the oh-so-important texturing is a vocation in itself... THEN you have get the geometry and physics and contact points figured out... Dynamic virtual cockpits are a test, too. Oh.. and don't forget the panel(s)

(if you have a wedding planned for the near future, you might wanna choose between your new bride and aircraft modeling
