If you're looking for a profound, long and spiritual underrated baroque piece to play, you should give a try at Henrich Ignaz von Biber's "Passacaglia" masterfully transcribed for guitar by Dieter Kreidler (Schott GA 471).
It's not the famous "guardian angel" for solo violin, which ends the cycle of the "Mystery sonatas" (and paved the way for the otherwordly Bach's Chaconne), but a transcription of the sonata VI for violin with basso continuo. Originally transcribed for solo lute by an anononymous monk in the Kremsmunster Manuscript, it lends itself very well on the guitar, and it's not as difficult as the "guardian angel".
Only lute versions are to be found on YT. I'm eagerly waiting for the first guitar rendition...
