I was given The Barbell Prescription[1] by a friend for my 40th birthday.
It is pretty thorough in suggesting why weightlifting (or rather; resistance training) is more important than endurance/cardio. In summary: they train different muscle types, and the anaerobic types age worse than e.g. the heart, so it's better to focus on that. They do suggest that you complement it with some cardio exercise, but it's a side gig rather than focus.
