Lot of good advice so the only things I'll add are:
Consider the tasks you need/want to do and consider the time you'll have to do them (if you already haven't). There's a lot of tractor sizing advice out there, but so much of it focuses on the tractor rather than the user needs/tasks and the timeliness of completing said tasks. .....and as much focus is put on tractors they're really just tools (or more appropriately tool carriers) and they shouldn't drive the purchasing/sizing decisions themselves. It's that identifying of tasks and time allowable, along with any max/min constraints (e.g. loader lift capacity) that tends to be much more helpful in determining the size of the implements/attachments you'll want/need to purchase which in turn drives the size & power of the tractor along with any additional options that would be helpful to add to the tractor upfront (e.g. rear remotes, top & tilt kits, 3rd function valves on the loader).
Something else that may be worth considering is how much driving around the property you'll be doing with this tractor; from what I've seen it's usually the case that the smaller the tractor the lower the top speed. So while mowing along a fence line isn't exactly a high-speed endeavor having a bit more speed to get back in once you're done can be rather nice and at low at low speeds a few extra mph can make a difference. Another place that extra speed can come in handy is shuttling back and forth when you're doing loader work.
While it's been a few years since I bought mine, I still recall that the "bang per buck" generally got better going larger as the price difference between sub-compacts and various sized compacts isn't all that great when considered over the life of any loan (and with the low/no interest rates :confused3

-- or the expected life of the tractor. Granted going larger/heavier can also add transportation considerations (if moving the tractor to other properties is part of the task list).
Not trying to undo anything you've researched or analyzed, just wanting to ensure that a few things that seem to frequently be overlooked aren't. Though even when everything seems to point that the tractors you're looking at are appropriately sized, it's probably still worth talking to the dealer(s) about how low hour trade-ins are handled if it turns out the initial tractor you go with doesn't quite fit your needs in practice (was actually a conversation topic my tractor dealer brought up with me when I bought my current tractor).
Anyway just my :2cents:
