  We present a broad analysis of X-ray polarimetric observational prospects for
radio-quiet active galactic nuclei (AGN), focusing on the role of parsec-scale
components. We provide a revision of self-consistent type-1 and type-2 generic
AGN radiative transfer models that were obtained with a Monte Carlo code
STOKES, evaluating the effects of absorption and scattering. Our model consists
of a central disc-corona emission obtained with the KYNSTOKES code in the
lamp-post geometry, an equatorial wedge-shaped dusty torus and two symmetric
conical polar outflows. We argue that the information on the mutual
orientation, shape, relative size and composition of such components, usually
obtained from spectroscopy or polarimetry in other wavelengths, is essential
for the X-ray polarization analysis of the obscured type-2 AGNs. We provide
general detectability prospects for AGNs with 2-8 keV polarimeters on board of
the currently flying IXPE satellite and the forthcoming eXTP mission. Finally,
we assess the role of contemporary X-ray polarimetry in our understandings of
the unified AGN model after the first year and a half of IXPE operation.
