This closely approximates what I've gunned for. I'm not aiming to be a maximalist, but want my investments to be worthwhile. My intuition has suggested to me that with cardio (moderate/intense), a little goes a long way and long sessions can eventually yield injury. You mentioned not bothering with citations but if you recall any sources I'd check those out. You didn't mention it, but the other benefit of strength training is higher testosterone levels.
