What about rugby, hockey or lacrosse? All physical sports to varying degrees and would cover most of the things you mentioned.Basically you are anti-football then. It is your business what you do with your son, but keep in mind holding him out of football could actually do more harm than good. What other sport will you put him in then which will build as much strength, cardiovascular health, bone density, balance, agility, mental toughness, and provide enjoyment for his life?
Someday if he is drafted into the armed services, or decides to become an officer of the peace, what other sport will have provided useful background in physical contact, posture, and agility to help save his life?
Second, the dangers behind CTE and brain trauma are real and quantifiable. I don't think we should be shaming parents for their decision to keep kids out of the sport, especially in the small chance they join the military or some other law enforcement. Perhaps that's not your intent but it certainly seems like it.
