I wouldn't squat 3 times a week.
If I could only train 3 times a week, I would either use a 2 way split like upper/lower, OR I would use an A and B total body routine, so that you hit each workout 3 times over 2 weeks. Week 1 would be A-B-A and Week 2 would be B-A-B
The 2 way split might also have an A and B variation.
So an example would be
1A) Squat then Deadlift
2A) Bench press and clean high pull
1B) Squat then Front squat
2B) Standing press and Chin-up
Again training 3 times a week would look like this
Week 1) 1A 2A 1B
Week 2) 2B 1A 2A
Week 3) 1B 2B 1A
Week 4) 2A 1B 2B
