What kind of websites will we be able to publish with heavy use of CMS in Figma Sites?

So, after testing 1st beta release of CMS I can ensure everyone that they can create blogs, web books and guides thanks to collection editing and usage of multiple rich text fields.

I wonder whether there will be improvements that could support huge CMS collections, sorting, choosing which items to publish and which ones to hide from publishing, duplicating items and collections, changing order of collections.
