can't speak for OP, but your final sentence is part of the reason both myself and many others don't prefer squats. For many, once you get to a certain weight - a weight that is a challenge and/or the weight you need to be at for more growth - it can be hard to balance that against maintaining proper form. This of course leads to back pain, some people get back pain from squatting even with proper form, as well as keeps you from squatting at depth. Squats are also a challenge if you don't have great mobility, especially in the ankles/feet. Lastly, can be hard on the wrists, especially front squats.
This is why you use the Smith-machine squat and bench was it eliminates the balance issues and allows you to focus on strength and form soley.
It's not all about heavy weight, remember most women with great legs dont squat more then 145 and yet they get thick legs all while having low testosterone, that should let you know it's not all about strength=,size
