Welcome to this list!  You seem to be doing fine all by yourself in your
gradual accumulation of CDs and I suspect that if you continued acquiring
CDs based simply upon what struck your fancy you'll be compiling a
collection that will give you as much pleasure as if you were following
someone else's prescribed list.  That said, I notice that, aside from the
Schubert and Schumann Lieder cycles, your collection consists of works for
large ensembles (Operas, choral works, and orchestral works).  Might I
suggest some works for piano solos and chamber music, including quartets,
quintets, trios, etc.  Others will no doubt make specific suggestions.
Follow them or your own intuition.  Enjoy!
