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.
I think both are important. I love running and started it first but ended up injuring myself and couldn't run for a number of years. Lifting fixed the issues I had and allow me to run consistently. The body you build with weight lifting is, in my opinion, a more aesthetically pleasing one as well.
Ideal would probably be a mix of resistance training, maximal intensity-metabolic conditioning work (sprints/HIIT/plyometrics), and low intensity steady state cardio (i.e. zone 2, cardio at the pace.you can hold a conversation). Each has unique benefits.
Both are important. My elderly father's doctor recommended he start lifting weights. My father already gets a reasonable amount of aerobic exercise, but they do different things for the body.
