  The effect of multiple topological transitions for electron-hole excitations
is discovered in full shell proximitized semiconducting nanowires with trapped
superconducting vortices, recently shown to be a promising platform for the
realization of Majorana states at moderate longitudinal magnetic fields. The
mechanism of such multiple transitions is uncovered and explained to be
governed by the interplay of normal and Andreev reflections from the shell and
by the textured spin-orbit coupling inside the semiconductor. The extensive
analysis of emerging propagating and Majorana-type evanescent quasiparticle
modes in such Andreev waveguides is performed. Experimentally, these modes
reveal themselves in peculiarities of charge and spin-polarized heat transport.
