We study the phase diagram of two different mixed-dimensional t-J_z-J_⊥-models on the square lattice, in which the hopping amplitude t is only nonzero along the x-direction. In the first, bosonic, model, the spin exchange amplitude J_⊥ is negative and isotropic along the x and y directions of the lattice, and J_z is isotropic and positive. The low-energy physics is characterized by spin-charge separation: the holes hop as free fermions in an easy-plane ferromagnetic background. In the second model, J_⊥ is restricted to the x-axis while J_z remains isotropic and positive. The model is agnostic to particle statistics, and shows stripe patterns with anti-ferromagnetic N{\'e}el order at low temperature and high hole concentrations, in resemblance of the mixed-dimensional t-J_z and t-J models. At lower hole concentration, a very strong first order transition and hysteresis loop is seen extending to a remarkably high 14(1)% hole doping.
