  Based on modifications inspired from loop quantum gravity (LQG), spherically
symmetric models have recently been explored to understand the resolution of
classical singularities and the fate of the spacetime beyond. While such
phenomenological studies have provided useful insights, questions remain on
whether such models exhibit some of the desired properties such as consistent
LTB conditions, covariance and compatibility with the improved dynamics of loop
quantum cosmology in the cosmological and LTB sectors. We provide a systematic
procedure to construct effective spherically symmetric models encoding LQG
modifications as a $1+1$ field theory models encoding these properties
following the analysis in our companion paper. As concrete examples of our
generalized strategy we obtain and compare with different phenomenological
models which have been investigated recently and demonstrate resolution of
singularity by quantum geometry effects via a bounce. These include models with
areal gauge fixing, a polymerized vacuum solution, polymerized junction
conditions and an Oppenheimer-Snyder dust collapse model. An important insight
from our approach is that the dynamical equations care about the $\det(e)$ part
rather than the square root of the determinant of the spatial metric. As a
result, shock solutions which have been argued to exist in some models are
found to be absent even if one considers coordinate transformations.
