If you are cleared for swings and cleans than you might be also cleared for armbars. If so, I would recommend you to give them a try and see if they work well for you.
I used armbars successfully to regain mobility, stability and motor control in both shoulders (unrelated injuries separated by 2 years).
I had mobility issues in my left shoulder a while back and couldn't maintain over-head ROM that I gained with hard and lengthy mobility work. That was right around the time I read
Movement so I figured that stability and control work where the missing ingredients. Lacking the confidence go over-head I tried one armbar on each side, felt good, increased ROM and confidence, added couple more, worked well... I rarely went for more than 3 each side a day with, a load that was just a little challenging. Adding some bent armbars along the way really helped with some thoracic mobility issues I apparently also had.
Based on some reading smart people stuff* I think that the rich proprioceptive environment is the key here (just like in TGUs and other self-limiting activities) and that one can reap a nice share of the benefits from TGUs without the need to go over-head.
