Just a reminder.
Most of us on here are older and nursing chronic injuries. It's not a question of "are they good exercises?", it's are the appropriate for you, are you performing them correctly, and is the load appropriate?
I have chronic back issues including surgery. Heavy squats irritate it and I believe likely accelerate my progression to a possible fusion in the future. Therefore, I use a curling bar with about 50-60# max across my chest in a front squat position so I lighten my load and ensure good posture for the lift.
The impact of jogging also inflames my disc. I use the lifecycle and elliptical instead.
Ditto for deep/heavy squats with knee meniscus or arthritis issues.
