My 13yo is deliberating this as well. He starts HS in the fall. It is high academic HS with a strong emphasis on volunteering. The kid informed me he wanted to forego fall sports so he could acclimate to the new school environment (yay, maturity). He does want to do S&C 3x a week in the fall. I suggested to start ol/ul swings in October, then lessons in Nov. He will do Driveline in December to ramp up his arm.
