I’d skip the Santa Cruz largely since Hyundai/Kia are experts at cost-cutting that blows up big in customer faces down the line. (anti-theft, engines, warranty work, wiring, etc.) but your options are already limited so I wouldn’t blame you for getting it. I’d get the base engine/transmission though if you anticipate stop/go traffic or off-road use since the dual-clutch in the upper engine option is better than dry clutch models but IMHO still suspect.
I would lean towards the Maverick but neither are really “small” since they’re still pretty long.
There’s the Transit Connect if you want a cargo van that’s compact.
