In the context of you quote, I was reading that you wanted to monitor/stay in the "cardio zone". In this context lifting heavy weights would not strictly do this as you would get close to your max HR when lifting and drop down again while rested. People generally lift heavy weights to gain strength and/or muscle, with cardio benefit as a bi-product. A heart rate monitor could be useful, particularly to see how quickly you recover after set of low rep heavy lifts.

For the running - yes, I do that for cardio health and long-term endurance. I tend to stay around 150bpm or so (my resting rate tends to be in the 55-60 range) while doing the 7mph intervals.

But yes, Vegas isn't great for running. Few parks with decent paths, sidewalks also not great. Also, most months, terrible sun. I've been beaten genetically where sunlight is concerned (not the heat, the UV).
I'm not sure how accurately HR maps onto CNS fatigue for maximal weight lifting. Since you don't really accumulate a lot of lactate unless you're doing muscular endurance work, it won't elevate quite as hard as repetitive high-speed movements, usually. I wear one when I lift, but I haven't gotten much information- the HR doesn't spike like it does during 5-10 second sprints, and I recover down to normal "warmed up" HR within 30 seconds usually. I've heard that HR variability is a good measure of CNS fatigue, but most monitors don't measure that, and the ones that do are meant to be used early in the day, not mid-workout
