Simulators are not perfect. Even if the flight physics match the real plane perfectly, the flat screen of a computer will not give you the spatial awareness you get from flying outdoors.
IMO, simulators are great for warming up your fingers, getting used to flipping more switches when you start flying planes with more than 4 channels, and learning how different design configurations behave (ie: jets, vs propellers, gas vs. electric, turbine vs. EDF, high wing vs. low wing, long vs short wingspan, high vs. low aspect ratio wings, tail heavy vs. nose heavy CG, high wing loading vs. low wing loading, etc.).
So I'd say in RF, pick any low wing bird as similar to the Commander as possible, practice on that, experiment with your simulator environment a bit (wind direction / speed / gusts, CG), and you'll be fine.
That being said, I do also wish every single EFlite plane ever made had an official simulator version. It would absolutely help them sell more planes.
Maybe that would come true with the new RF Evolution and its future DLCs
