It's somewhat of a false dichotomy as well, right?
Whatever you're doing for "cardio" also works "strength," and whatever you're doing for "strength" also works "cardio." When I'm trailrunning, I definitely work "cardio," yet my legs get demonstrably stronger. Working in the gym supplements that. Every time the muscles are pumping, and heartrate is up, you're developing some degree of strength and some degree of cardio. For me, a consistent diet of trail running plus supplemental gym workouts and hiking with a pack works really well. If I can throw some biking in there, it's a plus from both a "strength" and "cardio" perspective. Talking about them in isolation doesn't seem productive. In my view, it's all "fitness."
