...and about 4 acres pasture where cows are, and will continue to roam.
^ This stood out for me -- everything else you described a tractor in the size range you're looking at would work. However, if you have to deal with hay bales (especially large round or large square bales) then you're going to want to look at the loader capacities as that may drive you into a larger tractor sizes pretty quickly. Likewise, should you ever need to deal with unexpected carcasses that may also require higher loader capacities.
From my own looking *most* tasks can be done with any size tractor - however, there are some tasks that quickly run into minimum performance requirements in lifting capacities and/or PTO power requirements --- and dealing (either moving or making) with (hay/straw/etc) bales was one of them.
That can be worked around (to a degree) by using small square bales, but those are generally sold at premium prices (from what I've seen) and they may not always be as readily available as the various sizes of large round/square bales.
