  High-precision cosmic-ray data from ongoing and recent past experiments
(Voyager, ACE-CRIS, PAMELA, ATIC, CREAM, NUCLEON, AMS-02, CALET, DAMPE) are
being released in the tens of MeV/n to multi-TeV/n energy range. Astrophysical
and dark matter interpretations of these data are limited by the precision of
nuclear production cross-sections. In Paper I, PRC 98, 034611 (2018), we set up
a procedure to rank nuclear reactions whose desired measurements will enable us
to fully exploit currently available data on CR Li to N ($Z=3-7$) species. Here
we extend these rankings to O up to Si nuclei ($Z=8-14$), also updating our
results on the LiBeB species. We also highlight how comprehensive new high
precision nuclear data, that could e.g. be obtained at the SPS at CERN, would
be a game-changer for the determination of key astrophysical quantities
(diffusion coefficient, halo size of the Galaxy) and indirect searches for dark
matter signatures.
