Theory around the Cellular Sheaf
$begingroup$
I have lately stumbled upon cellular (co)sheaves, which look very interesting. To understand them better, I would like references that systematically develop the theory behind them (preferably in categorical fashion), and/or provide geometric intuition for their workings.
So far, the best source of information I have found is Curry's Sheaves, Cosheaves, and Applications.
All recommendations are welcome. In particular, I am also looking for Shepard A.D's 1985 thesis A Cellular Description of the Derived Category of a Stratified Space, a copy of which I have not been to find anywhere.

The two sources you mention (Curry and Sheppard) are literally the only references out there, and as far as I can see, both liberally use categorical terminology. What are you looking for that can't be found there?

Robert Ghrist's Elementary Applied Topology defines and works with cellular sheaves in chapter 9. He doesn't introduce category theory until later, but he is good at giving geometric motivation and applications.
