I went down that same road last year when I built an adjustable camera rig for my workshop videos. What helped a lot was switching to a linear actuator with potentiometer because it gives you real-time position feedback instead of just “fully in or fully out.” I paired mine with a simple controller and did some basic calibration so I knew what voltage range matched each position. It took a bit of trial and error, but once set up, it was super repeatable. This is the exact style I used: https://www.progressiveautomations.com/products/linear-actuator-with-potentiometer linear actuator with potentiometer. Biggest tip is to take your time with calibration and label your wiring clearly.
