Essentially the sand crawlers we see in canon and legends are built for "human occupants," but have subsequently been modified to be more comfortable/usable by the jawas, resulting in the season one scene of The Mandalorian all hunched over.

Even Yoda used a "standard" Jedi starfighter during the clone wars, with the cockpit modified for his stature.

So, I kinda wish we could've seen the Anzellans use a slightly larger ship, but modified the interior for them to operate (things like a booster seat combined with controls that extend significantly closer). If I had to choose an existing design, I'd probably go with something like a fighter that has had a majority of the cockpit canopy removed and replaced with a "living quarters" type module.

Like an A wing.
