I’ve “always” done front squats and no regrets here.
First year of training I worked up to a few crappy reps at my bodyweight, then started from scratch the last six months (I’m not really built to squat) and currently getting very close to hit 1.5bw with good form, which is my short term goal. Started doing them since I’m not followed by anyone in the gym and the front rack position felt safer when I didn’t know how to handle even an empty bar, kept doing them when I saw the major benefits: like you, I don’t compete, don’t plan to do it, and front squats have done wonders for my overall mobility - ankles, knees, shoulders, wrists. I think they’re one of the major contributors, if not the single main contributor, to my posture improvement, especially in the thoracic spine. Also, core stability.
They gave me hell at the beginning but after I nailed down the correct stance, mechanics and positioning, they kept giving me benefits and paid huge dividends imho.
And, for me too, the plan is now to keep front squats as main squat and back squats for volume and mass.
I decided about an year ago that my own big 3 would have been deads, front squats and the press since they’re the lifts I enjoy the most and being strong-ish even in just one of them is quite relevant for a mere mortal like me who just likes to lift.
I’m not strong at all but, in my limited experience, yes. I back squatted three times in my life, all recently, and I could back squat (while fatigued) more than I can front squat, actually. The back rack position is a breeze compared to the front rack.
I’m fairly sure I’m back dominant so keeping the front squats is a bit of extra challenge and, so far, I didn’t feel the need for extra posterior chain stuff - maybe in the future if it’s needed
