Personally, I'd go for a typical high wing trainer. While you do have some experience with RC flying, which will be extremely helpful, the planes you mentioned are not going to be the same as what you will be stepping up to.

On option might be to get a more "advanced" trainer. Something like the Hobbico Avistar or World Models Skyraider Mach-1 both have semi-symetrical airfoil and shallow dihedral. This makes them better at aerobatic maneuvers but they are still relatively gentle and forgiving.

I would also ask around at your local club and see what is popular there and what they recommend.

The bottom line is that there is nothing wrong with a high wing trainer. You'll likely even see a lot of experienced pilots at your club playing around with one from time to time.
