Lotsa time in the 1-D, second choice 51D.
When I was new to sims, I'd pick a plane and fly it for the tour. You get experience in quite a few, learn what they can do, and can't. A little of everything, Spits, 109's, 190's, P40's, zekes etc.
Then apply what you've learned to your ride of choice. You then have a handle on what the other plane can do, and more importantly, what it can't vs. your ride of choice.
I got hooked on 190's for a couple of years
