If you're running AC up the tower, there are probably wide voltage DC
transformers (100-240v) for everything up top that would clean it up
anyway. We have a 200' Grain leg where we have an APC 750 UPS at the
bottom. 120vac on #12 wire to the top and nothing has ever complained.
There are several Meanwell AC/DC transformers at the top for 24v/48V,
along with normal POE injectors (ubnt/cambium). I've never measured the
voltage drop, but it has never been an issue.

Are you doing DC up the grain leg or AC?

It's a square wave which a transformer would clean up. The drop
wouldn't change and a buck-boost would up the voltage for the
end-point.

We are considering moving our APCs down to the bottom of some of
the grain elevators we have our enclosures up top of. There are a
multitute of reasons for this, right wrong or indifferent.
The concern i have is the voltage drop. The output of APC UPS as
I understand is not pure sine wave, but a square wave. Will this
impact voltage drop calculations?
