Seconded on goblet squats.
I don’t do them very heavy (about 25% of my bw) cause they’re at the end of my workout, but keep the dumbbell pushed against your chest, brace by filling in air and actively pull your shoulders and ribcage down, keep a proud chest during the movement and you’ll really feel the upper back working.
They’re also a good tool to focus on other squatting cues and reinforce habits (spread the floor, knees out, sit into the hips etc etc).
As for front squats programming - as a generic rule, can’t go wrong with 5x5FSL. If you want to push them, you might want to pyramid down during the cycle, doing for example 5x5 SSL on the “5” week, 10x5 FSL on the “3” week and 5x5 FSL on the “1” week - this really depends on the rest of your workout and how you feel after deads and so on.
I’ve never done 10x5 on front squats so I can’t vouch for it, it might or might not fatigue you too much. 5x5 SSL on the lightest week and 5x5 FSL on the other two weeks should be optimal, tho.
Definitely avoid 5x10 or any other high-reps scheme (like 1x20), they work best for lower reps - I’ve been doing them as main squat movement with PR sets and keeping up with doing 7-10 reps on top sets is not optimal.
Obviously, you’ll need to know your TM, you could either test the 5RM on your next deload or go by eye and try to base it on your back squat %.
