Although cardiovascular endurance is important, the training for it doesn’t do for us what strength training does. A heavy set with a big, compound barbell lift can be scary. A long run is just boring. Heaving the barbell strengthens my resolve. Pounding the pavement makes me tolerate tedium.

Perhaps this is why office workers [and maybe police and military personnel] prefer cardio over strength training. It prepares them for the drudgery of their jobs.
