"Categorification" is an ugly term that has been used to suggest every sort of undefined garbage. Please refrain from further such pollution of the landscape of modern science. Thank you.
In particular, Mac Lane did no such thing. His paper "Duality for Groups" in the Bulletin of the AMS 1950 made clear that in any category where finite coproducts are naturally isomorphic to products, there is a unique definable addition of parallel arrows so that maps between products are uniquely representable by matrices of smaller maps.
Of course there is no unique decomposition of objects as products, so it would be completely wrong to suggest that maps "are " matrices. This is actually briefly discussed earlier in the book.
