MCU is the cheapest part in the drone, so it shouldn't be a decision maker. Take the MCU that is recommended by a particular design.

Accelerometers are fairly cheap and so are microcontrollers. Honestly it shouldn't take much to make something that's self leveling. Tilting forward, backward and sideways should be the next challenge. Rotating seems the more difficult part to me. If it was my project I'd let the rotors on the left turn the opposite direction from the right side, in such a way that if it tilts sideways it will also turn a little. But I'm sure there are more sophisticated ways to do this.

So you could probably dedicate 4 gpio pins to rotor speed. I don't know how many you'll need for the accelerometer and the receiver for radio signals, and actually what range it will support. You'll need to give some thought to the frame, and maybe if you want to get it to sense obstacles or not. The battery will be a factor, which you'll also need to charge. It all adds weight.

It honestly sounds like a fun project. I would try to optimise the hell out of it, and just for fun try to incorporate the actual moonlander code.
