The 5x5 stuff looks quite the same as what I wrote (stolen from Rippetoe) with a bit more volume. No reason it wouldn't work just the same.
I do think that most everyone benefits in many tangible ways from focused strength training, neglecting cardio stuff as needed for the time duration it takes to get strong. Like I mentioned, the cardio is the easiest to get back. Try getting a larger strength base first before altering training to maintain strength and increase work capacity.
