Always tired. Fitbit tracker says low sleep efficiency. Videotape confirmed constant tossing during sleep. Should I do a sleep study? Recommended tx?

Consult sleep clinic. Good sleep helps you feel healthy and vital. Sleep apnea (frequent awakenings due to low oxygen levels during sleep) can increase your risk of high blood pressure, heart rhythm problems, and even obesity! so consult a sleep doctor. If necessary, they will recommend a polysomnographic exam where they monitor your vital signs, movements, oxygen levels, and video your sleep in an overnight sleep lab.
