Graham showed with Pollak and Hoffman-Hosoya that for any directed graph $G$ with strong blocks $G_e$, the determinant $\det(D_G)$ and cofactor-sum $cof(D_G)$ of the distance matrix $D_G$ can be computed from the same quantities for the blocks $G_e$. This was extended to trees - and in our recent work to any graph - with multiplicative and $q$-distance matrices. For trees, we went further and unified all previous variants with weights in a unital commutative ring, into a distance matrix with additive and multiplicative edge-data. In this work: (1) We introduce the additive-multiplicative distance matrix $D_G$ of every strongly connected graph $G$, using what we term the additive-multiplicative block-datum $\mathcal{G}$. This subsumes the previously studied additive, multiplicative, and $q$-distances for all graphs. (2) We introduce an invariant $κ(D_G)$ that seems novel to date, and use it to show "master" Graham-Hoffman-Hosoya (GHH) identities, which express $\det(D_G), cof(D_G)$ in terms of the blocks $G_e$. We show how these imply all previous variants. (3) We show $\det(.), cof(.), κ(.)$ depend only on the block-data for not just $D_G$, but also several minors of $D_G$. This was not studied in any setting to date; we show it in the "most general" additive-multiplicative setting, hence in all known settings. (4) We compute $D_G^{-1}$ in closed-form; this specializes to all known variants. In particular, we recover our previous formula for $D_T^{-1}$ for additive-multiplicative trees (which itself specializes to a result of Graham-Lovasz and answers a 2006 question of Bapat-Lal-Pati.) (5) We also show that not the Laplacian, but a closely related matrix is the "correct" one to use in $D_G^{-1}$ - for the most general additive-multiplicative matrix $D_G$ of each $G$. As examples, we compute in closed form $\det(D_G), cof(D_G), κ(D_G), D_G^{-1}$ for hypertrees.
