That can be answered a couple of ways.
Yes, there are LOTS of new works, some of which are very well-considered musical constructions. Angelo Gilardino's various Sonatas come to mind. Marek Pasieczny is another significant composer of heavy gauge modern CG works. For myself, I prefer the lighter fare of modern composers such as Jean-Marie Raymond, Maria Linnemann, Per-Olav Kindgren, Giorgio Signorile, Yves Carlin, and so forth. None of these make any claims toward being Serious Important Music, but it is enjoyable to me and to many others even though these works won't likely hold up through the coming decades.
But to the best of my awareness, NONE of these modern works, large or small, have (yet) become Core Repertoire Standards. Usually these pieces are in the repertoires of the composer or the work's dedicatee, or of a few "fans", and are not often taken up by others.
That said, the CDs and YT videos of many of these and other recently written pieces are readily available.
