MongoDB supports indexing of nested and array properties and has a 16MB document size limit for BSON documents. Those things help a lot in a CMS; if you prettyprint an Apostrophe page in MongoDB the structure just pops out at you. We've had good experiences hosting it both with the community edition and with Atlas. When your documents make up a page tree and have a lot of structure within each document that would otherwise involve extra joins, it's a nice representation and we really haven't paid a price for using it. If we had, we might have made other choices. YMMV.
