The "rest" of the standard model, which is considering the question, what's "the matter content of the universe" then is based on finding the gauge groups and their representations leading to consistent local QFTs describing the observations, and that has been found by an interesting interplay between theory and experiment, and it's very likely not to be finished since the SM most probably does not provide the complete set of fields/particles needed to describe all observations (in terms of the cosmological standard model what is the "dark matter" made of needed to get the amount of "clumping" to form the observed inhomogeneities like the galaxies, galaxy clusters, and so on, as well as an understanding of why the cosmological constant/dark energy density takes the small value it does).

Okay, so simply put, everything is Minkowski spacetime and mass, and ultimately all information--energy, force, quantum spin etc.--can all be boiled down to aspects of those two things. Is this an accurate simplification?
