  We theoretically consider the spin Seebeck effect, the charge Seebeck
coefficient, and the thermoelectric figure of merit in superconducting hybrid
structures including either magnetic textures or intrinsic spin-orbit coupling.
We demonstrate that large magnitudes for all these quantities are obtainable in
Josephson-based systems with either zero or a small externally applied magnetic
field. This provides an alternative to the thermoelectric effects generated in
high-field ($\sim 1$ T) superconducting hybrid systems, which were recently
experimentally demonstrated. The systems studied contain either textured
ferromagnets, spin-active interfaces, or spin-orbit coupling. We present a
framework for calculating the linear thermoelectric response for both spin and
charge of a system upon applying temperature and voltage gradients based on
quasiclassical theory which allows for arbitrary spin-dependent textures and
fields to be conveniently incorporated.
