  Two-Higgs-doublet models (2HDMs) with a flavored U(1)' gauge symmetry are a
popular extension to the Standard Model (SM), yet they currently lack a
complete survey. In this paper, we present a full classification of
anomaly-free 2HDMs within the SM fermion content, resulting in a total of
eleven distinct models. Four of these are relatively well-studied, while the
rest either partially, or entirely, lack previous treatment. We study these
textures under a variety of experimental bounds, focusing mainly on the
previously unexplored models. This work is intended to act as a catalog to
models worth considering in greater detail.
