#2So the sicker you are the less in shape you are in? Seems obvious to me.

#3The Apple watch has a decent cardio fitness monitor. The absolute values aren't precise (since it uses VO2Max estimates, which is really only accurate if you're doing a metabolic stress test), but it's good to keep an eye on trends.

#4Slightly related:
I have been engaging in powerlifting/weightlifting for over a decade. In my initial years, I was in the "just do weights, don't need cardio" camp. However, around 2018, I started doing cardio mostly to cut body weight as I wanted to hit my personal bests on squats, deadlifts, and bench at a lower body weight.
I personally experienced that my weights moved much better, especially when I was doing more volume work (higher reps) with cardio than without cardio. Cardio seemed to improve my working capacity and I felt more efficient at doing more reps.
So, I would recommend cardio even when one is trying to bulk up in weight and trying to get strong. Doesn't have to be crazy cardio either - just 10 - 15 minutes of zone 2 cardio 4 days a week might be good enough. You can also do types of cardio which work certain muscles - like stair master can be made to specifically target the quads and calves. Or rowing can be good for building the lats. Swimming is good too.
Personally, I either do intervals on the stair master or intervals on an echo bike (fan bike).

VO2 max is also exercise dependent. If you trained riding bike for 3 months, then went to run down the street, your VO2 max would not transfer over.

Is that true? Back when I was a crew gremlin, my VO2 max as measured via erging was off the charts. But I could apply that cardio capacity to things like running/biking/swimming pretty effectively.

That's what you hypothesize. Research like this affirms your hypothesis with fact.
There are historically lots of things that "seemed obvious" but couldn't hold up under research, which is why we do research. It confirms what you think or maybe it forces you to question what you think. Either way, it is good.
Case and point, there is a rising opinion lately which Trump has promoted that your heart only beats a set, finite number, of beats in a lifetime. Therefore, according to this opposing hypothesis, it makes sense to not perform intense cardiovascular activity throughout your life, because it accelerates your heart hitting that finite limit that it is capable of. This opinion has gained traction in recent years and to some people it "seems obvious" that a faster heartrate might wear it out more quickly, leading to premature death. So to those people, research like this defeats their assumptions and helps them feel more confident about performing exercise because it is research-backed that Cardiovascular Fitness prolongs life.
That's why research is important. Obvious shouldn't stand for anything.

Note that there's lots of complaints about the VO2Max estimates on Apple Watch. For example, this reddit thread:

Non-intense aerobic exercise exercises a narrower metabolic aspect of your cells than intense anaerobic exercise. You have to be be very careful what you consider is beneficial "cardio".
