Here's what I usually do. I usually walk to & from the gym, anywhere from 6 -8 miles roundtrip depending on the route. Lift when there, about 3-4 days per week. 2-4 days per week I do official "cardio" ie elliptical via HIIT. Total cardio probably 5-6 days per week. I've been feeling exhausted doing it so I think I'll cut down.
