In general, common potentiometers can be perfectly used for this, at least for for throttles, mixture, prop, rudder.
As for photo-resistors, I've been often using the LEDs/Photoresistors for main axes before. When it was a simple "Game controller" input for joysticks the only one sensor was used as 100k photoresistor.
When Arduino analog input is used we need a pair of "differential" photoresistors connected as a potentiometer.
Each of them is lighted by LED. When LEDs are moving with the yoke, resistance of one photoresistor is increasing, while the other is decreasing.
In Baron simulator I've implemented the following schematic:
Also, you can try different mechanics, for example the rotating (tilting) LEDs as I have pictured on the diagram here:
