  Multiband superconductors have featured one of the main challenges to achieve
a comprehensive understanding of unconventional superconductivity. Here, the
multiband character is studied separately as orbital and sublattice degrees of
freedom, as they have different effects for the superconducting and magnetic or
charge orders. We build on the framework of the matrix random-phase
approximation (RPA), which accounts for the RPA Feynman diagrams and also
vertex corrections, to treat the electron-electron interactions in an off-site
degenerate Hubbard model. As a result, systems without a sublattice degree of
freedom tend to be dominated by spin fluctuations, while systems with multiple
sublattice sites and orbitals have the charge fluctuations favored. Finally, we
explicitly demonstrate that the known suppression of the superconducting
pairing strength $\lambda$ by spin fluctuations from repulsive interactions at
zero momentum transfer $\boldsymbol{q}$ is countered by the
finite-$\boldsymbol{q}$ pairing, which always improves $\lambda$.
