Have you considered pinboard.in? Not fancy, but fast, cheap ($25/year for the full version that also crawls and archives everything you link to). Syncs with both Instapaper and Pocket. I find it to be basic, but good enough for both bookmarking and read-later functions. Notes can go in the Description field but that may be too much of a kludge.
