https://noblesofnull.com/wiki/m-216_paxton <--- What we have so far on the matter.
I'm including tanks in this discussion. The way I see it, there are a few theatres of combat of concern for AFV's: Open field, symmetrical warfare on Earth, urban warfare, low gravity, open field, symmetrical warfare, low gravity, urban warfare, and open field, asymmetrical warfare.
Open field, symmetrical warfare
Here, we would see MBT's the most. Their heavy front armor and heavy weaponry spearheads assaults and protects lighter units moving up from the rear. However, MBT's even in the 21st century are vulnerable to airstrikes, and increasingly vulnerable to mines, infantry anti-tank weapons, etc, making them even more situational in the 24th century, a small piece in a very complex puzzle of open field combat.
Urban warfare
The urban environment completely kills MBT's as a concept, but the need for mobile armor to fulfill support roles and carry heavy firepower still persists. Light tanks with better distributed armor comes to mind, small enough to navigate narrow roads, but large enough to carry infantry, sensor equipment, or autocannons. Like their MBT counterparts on the field, these urban AFV's require extensive support to be effective in the form of infantry, ground and aerial drones, and air support.
Low gravity, open field, symmetrical warfare
Likely the rarest environment for combat as spaceships and missiles will dominate the "air"space and infantry will want to assault stations directly, but the niche is still there. Perhaps the greatest asset here is stealth, the ability to hug a body's curvature to avoid detection. Thus, niche AFV's can exist to serve as missile platforms, recon, and troop transport. Low gravity environments serve as experimental testbeds for alternative modes of mobility: wheels and mechs.
Low gravity, urban warfare
The same rules apply here as with urban warfare, except special consideration must also be made under the underside of AFV's, since space stations are truly three-dimensional spaces. Wheels and tracks will also fail when gravity systems go out. Thus, mechs and crawlers may find true, viable niches in these environments, but infantry and drones will dominate almost all aspects of combat.
Open field, assymetrical warfare
This environment primarily exists on planets dominated by a single supernation that has firm control over all infrastructure. The opponents are pirates and small time rebels with limited resources and technology. AFV's will prioritize fast response: mobility and only moderate firepower, serving to combat other vehicles, and as mobile command posts, relay stations, and supply depots.
