We perform a systematic classification of (2+1)d Gross--Neveu--Yukawa-like models built out of one or more 4-component Dirac fermions and M scalar fields, which preserve an O(M) symmetry rotating the scalars. We then identify the perturbative fixed points of these models in the 4-ε expansion. Our classification highlights several targets for the conformal bootstrap and reveals a new fixed point with M=3, which we call the "orthogonal Heisenberg" CFT.
