They're also the two most injury prone lifts, and I think unless you are playing a sport you shouldn't put much effort into either of the lifts.

No. Bench is the lift that has the most injuries. Probally due to more people benching but still its number one in the injury department. I would say squating and deadlifting has alot of benifits for people not playing sports. Big compound movements like these help raise your bodies natural testosterone production which is benificial for putting on muscle mass and reducing body fat. They also develop more functional strength. Meaning they translate into real world strength. The secret is to use proper form and leave your ego at the door.
