If I was just standing in it I’d tend to agree with you. But most every laboring job I’ve ever worked has put the exact same stressors on a boot as hiking and then more.Obviously, you've never been to Kodiak.
Watch Deadliest Catch. They all wearing Xtra Tuffs.
A little mud in warm weather equates to child's play.
Evidently arch support in the lug sole model works for you. I was the exact opposite in mucks. Firtst pair were the lugged model, while very warm they actually hurt my back after walking any distance. Switched to the first type you showed and can walk all day in them. But they,re not as warm for sedimentary hunting during extreme cold.Wore Lacrosse for man years.
Never found a pair that kept my feet warm. ( unless bought heavy insulation, then was so heavy thought I was wearing concrete shoes.)
Most were not comfortable for all day wear.
Decided on a pair of mucks, and have been wearing them for 20+ years.
I bought cheapest ones I could find, with the sole like this:

I learned they were great for lite work, but if I wore all day.My feet hurt.
Friend told me to by a pair with a sole like this:

I wore an extra ( older pair he had) for a day.
Even though they were older, broken in for his feet, they were comfortable. AND my feet never got cold.
I went the next day and bought a pair.
Ended up buying mucks for the wife and kids.
I would say a good measure of a boots warmth, is if a kid wears them and says their feet are not cold.
Like the OP, I have some ortho issues, partial amputation, fused bones/joints, pins and screws, nerve damage.
Mucks are my choice. Have 2 pair sitting in closest right now.
There is also a pair of Lacrosse sitting next to them waiting to be worn out, but the mucks always get used.
Light use 10-12 years
Medium use 7-12 years
