I agree with the most part for all above.
A good low wing warbird trainer would be a Worl Models T34. they fly great with a .46 TT engine
the WM Mustang would be good for later, even still flys great on a .46 TT

I would tend to try a low wing sporty plane first, before your warbirds, some of us went
straight to warbirds after the trainer and have mastered all quite well. I wont mention my
name, but I did, and I havent regreted going straight to a warbird, and thats all I fly now.
