Aw hell, cut to the chase here--if the mrs is anything like your picture there, get the one she thinks is sexy and get to work, the rest will figure itself out.
More seriously--unless I missed it we have no idea how much land you're intending to work with one, and what it consists of. As--a backhoe on a 35 hp tractor will just dig a septic tank hole, one on a subcompact will dig the hole for the distribution box. Both will trench, the little one 3' deep, the larger 6' deep. You mentioned 'landscaping'; the bigger the tractor the greater the chances of running into a wall. Mowing a lawn working round the house and shrubs, HST is better with a belly mower; mowing a field with a brush cutter a gear transmission works just fine and you don't have to hold a pedal down. PTO farming implements will require hp in the 35-40 range unless they're for just a small vegetable garden. You'll feel comfortable lifting up to maybe 600 lbs with the loader on a 35 hp tractor, 300 lbs on something BX23 size. On nice flat ground, the L3400 loader will just lift the engine out of the '65 Thunderbird, the BX1860 will just lift the engine out of a '2005 Focus.
Compared to tractors in the 50's and 60's, to an old guy all these things are impressively competent now, who would have thought that a BX25 size tractor could be made to do so much. Why not put some jobs together, take some money and go rent one for a day or two and see how you like it? I think a lot of talk could be eliminated that way; try one, all it can be is big enough or not.
And you'll find out whether the mrs thinks it's sexy; might be worth the rental fee right there.
