Kev-
I grew up hiking in boots. I not so fondly recall the hourly stop for "sock check", the 10-60 minutes a day with the "lug stick" digging out mud/rocks/crud. The not so infrequent toe kicking of trees. And the eeirliy wonky on the knee- foot flick.
Framing houses, I work in a lot of mud.
Point being, the good old waffle stompers with their hard rubbers, aggressive lugs, and deep tread just hold mud and debris. Eventually you're simply walking around in your own personal mud slick that tugs not so subtly on your knees each time you pick up your foot. I found myself using the claws on my hammer to pry muck out more often than nails. If a tread can't "throw" mud, then it just becomes a hunk of trail. IMO, none of the heavy tread boots beat this issue. The only thing they do well- is stay on your feet.
You may occasionally step out of your shoe with a low top- but you won't accumulate a 3lb crust along the way. You can also get a trail runner type shoe in a high top of course.
Not much microspiking in my neck of the woods- but as they work regardless of tread type or shoe design...
So, Yar- fer hiking in damn near any realistic regular conditions I can think of encountering when backpacking- the good ol' hard rubber, deep, aggressive lug sole is the worst.
After that- you nailed it. When it's really serious out, wither for warmth or mechanical attachments- a good pair of "real" boots is often the solution. No need to mess with the stuff in the middle.
Much to your credit- most folks will not take on the scrambling you do; a specialized application that a good approach shoe solves nicely.
This is my "aggressive" tread of choice for the serious stuff-
