For cycling, I do a long warmup then ride as hard as I can (uninterrupted) for 30 minutes and take the average HR for the last 20 of the 30 minutes. There are online calculators you can plug this value into to give you the 5 zones.*
I do a test every 3 months, as the zones can shift as you get fitter.
Running might use a different protocol, but the same principle applies.
* These days I base my training on a 3-zone system: low intensity, below aerobic threshold; medium intensity, between aerobic and anaerobic (lactate) threshold, and high intensity, above lactate threshold. This is the system preferred by researchers, as it's based on real physiological markers.
Translating the 3 zone system into the 5 zone: low intensity equates to zones 1-2, medium is zone 3 and zone 4 up to your (lactate) threshold value, and high intensity is everything above this, i.e. the top part of zone 4 and all of zone 5.
So 'vigorous' per the Mayo Clinic would be medium intensity on the 3 zone system.

If you're just using a formula your heart rate zones could be quite far out.
For example, 220-age suggests my maximum HR is 178 and my threshold HR (85% of this) is 151, but in fact my max HR (determined empirically) is 188 and my threshold HR (based on an actual threshold test) is 162.
Resistance training has innumerable benefits, but it's not a panacea nor is it a substitute for aerobic exercise; if done properly and sensibly, aerobic and resistance training complement one another. Here's a great summary comparing the two: https://www.researchgate.net/figure/Adaptations-and-Health-B...
By all means emphasize one over the other as you prefer, but for health benefits both should be included. And, no, powerlifting exercises with a straight barbell are not irreplaceable. Resistance training is a far bigger world than that.
