Even the C152 is a great plane to start in. Two Nav gauges with ILS and NDB (no DME). It’s nice and slow so you have time to get your bearings (pun intended), not a lot of systems to distract you, no autopilot so you have to do everything yourself, nice simple platform to learn in.
After you’ve gotten some training in one of the human run ATC groups, you can get some charts and start practicing on your own. A neat tool to use that’s free to start with (they would appreciate a small donation if you start using it to help maintain the servers for the charts and other data) if you’ve got an android tablet or phone is Avare. It has up to date NOAA charts and supplemental data and more for at least the US, you can update them for free every month. I wrote up instructions for how to use it with MSFS here. Of course there’s also Navigraph; I haven’t used it so I can’t speak to it. I use Avare for flight planning and as a backup GPS when I fly for real, too. I know people in Europe use it for flying, too, but I don’t know where they get the charts from. There is an Avare user group out there.
Make sure you have a good way to trim the plane though so you’re not worried about maintaining altitude. I set up the throttle axis on my Logitech Extreme3D Pro joystick as a trim axis (-100% - +100%, don’t use the other one), and it’s made flying soooo much easier (I’m not much of an autopilot user, I prefer to fly by hand like I do for real in Cherokees), much closer to real life. Granted I have experience trimming real planes, so, there’s something else to pick up, but, it’s not hard. It is a little sensitive, but, you can get it right on, as opposed to trying to set up buttons to move it up and down which is impossible to get right.
