Andrew Hunter's setup might be worth consideration, I've clipped this youtube to the bench part

Coupled up with Kris Harbour's saw horses or something else sturdy might be worth looking into.
If set on a fancy workbench, then I'd favour something like Schwarz's petite roubo, but without the through dovetails interfering with the top,
so back following along the lines of a floating top like Andrews, Scandi and a whole list of others.
I'd build a second set of strechers instead of relying on the top though, so it would be able stand on end for doorways less faff for moving.
There is just about the biggest compilation of various Roubo style benches on a massive old thread titled all replies on workbench smackdown , but you'd be there for a week with a pen and paper, which would be required to refer to.
Although possibly the nicest home workbench, I think a Scandi bench is about the last thing one would want... due to the third leg mainly.
It doesn't lend itself well to be in narrow spaces, should it be the case, can't say about inside the house, but think I stumbled across one used as an entertainment centre somewhere, cant be sure if it was though, sure looked pretty.
And if looking into the smaller size knockdown European benches... I wouldn't be confident about it not racking...
And mentioned an above post another option would be the Morovian bench..
Whilst I've seen demos on assembling the Morovian bench, who would be bothered?
Just saying, as the strechers and top would be the same length, not lending itself to get any shorter.
Infact the base might be just what you would want, should you have a short vehicle, with a top sticking out the back, if that matters.
Not to mention a protective structure around the important part, should you be of the Klaus Charlesworth Cosman etc.. persuasion, and use your bench
as a reference to get more from much it than other designs.
All the best
