I have a library that does a bit of a hybrid. A key aspect is to retain
enough structure to make high-order and composite finite element methods
efficient while still having reasonable performance for low order. I don't
think it's really what you're looking for because it just pulls out arrays
for most tasks (though it doesn't maintain a full mesh data structure on its
own), but I use sets and tags for some purposes. Be warned that it is quite
immature and since I don't have any users that I know of, I change things
pretty arbitrarily. There are also several places that assume hex elements
rather than work through the correct API. Let me know if you have questions.

MOAB/iMesh is not user-visible in a typical assembly loop, so Dohp is
probably irrelevant to you
