Interesting thread, so I'll weigh in with my opinion...
Back in 2012 I bought a new NH L220 SSL, & put rubber OTT's on it for flotation & traction, all in the hopes that it would allow my 1990 Ford 1320 4wd FEL to "rest" a little.
Turns out my 1320 is STILL my machine of choice, except for plowing snow, where the L220 is a joy, with a heated cab!! The big problem with the L220 is that it is too troublesome to get in/out often when I'm working by myself, which I always am. The 2nd problem is that the L220, even with OTT's, is rough on turf....as bad & maybe worse than my 9 ton excavator with 24-in wide steel tracks!! And the L220 is not great in mud because it doesn't have enough ground clearance.
So...If you're concerned about ground disturbance, don't get a SSL or a CTL. By their nature they are rough on ground. Possibly the only exception would be an ASV unit which has the suspended track system (also, a lot of ground clearance). The Cat MTL's, which also have the ASV suspended track system, don't do as well as the ASV's, because they lack the same weight distribution (& have much less ground clearance).
If you're still stuck on a SSL/CTL, & cab access is very important, then consider the side-entry JCB units (or Volvo's made by JCB). Their cab room, visibility, & ease of entry/exit is unsurpassed in the skid competition.
But in my opinion, if you want minimal ground disturbance, great ground clearance, cab spaciousness & ease of entry/exit, plus superior lift capacity, then your choice should be a compact wheel loader. In the common articulated type, Cat has it's smallest, the 903D (9,400 lbs), or the next size up the 906M (12,481 lbs) which might be too big.. Wacker Neuson has its smallest, the WL32 (7,500 lbs), plus a range of larger units. The WL38 (9,300 LBS) is one I'd be interested in. Gehl has it's smallest, currently the 650 (9,500 lbs), with some smaller units reportedly due out next year. All of these units (except the Cat 903) are capable of a top speed of 18 or more mph. And the Wacker & Gehl units have rear hitches available, particularly receiver hitches, as well as rear electric & hydraulic options. Go with a receiver hitch, insert a ball mount (without the ball), & now you have a draw bar to hook a drag to.
If the small loader size & articulating action is not maneuverable enough, then look at the Wacker Neuson AWS 5055 (7,940 lbs), which has all-wheel-steer instead of an articulated center. And still has the 18+ mph top speed & the same rear hitch, electric, & hydraulic options as the others.
If ultra-maneuverability is a must, then look at a REALLY small wheel loader, like an articulated Avant, but you give up the larger lift capacity of the units above.
All of the compact loader units above have a universal skid steer quick attach on the loader arms, so bucket & fork attachments are easy to get & change. And if you really want to go nuts, at least Wacker Neuson has some units that have telescoping arms that offer much longer/higher reach of doing things like stacking hay. Of course there is JCB's teleskid as well, but it's still a SSL or CTL.
The only disadvantage of a compact wheel loader that I can see is the overall height of the cab, if you're working in old barns. The wheel loader cabs are all in the 7.5 to 8 ft range, whereas SSL-CTL's are about a foot shorter, in the 6.5 to 7 ft range.
