I would probably add more features to make it usable as a CMS, rather than just a blogging platform. At the moment, custom fields are basically unusable without a plugin like Advanced Custom Fields, and the same is true of custom post types and formats, the user login system, etc. Lots of things that could make it a better general CMS are entirely left to plugins whereas they probably shouldn't be. I also don't get all the focus on full-site editing and blocks and customisation and Gutenberg either, since it feels like these features are only really going to be usable if either you're running your site as a solo venture or you're working in some sort of media environment where fancy one-off article styles can be the norm (like some New York Times longform pieces). Anything other than that feels like a place where the modern style of editor is just a recipe for disaster. A large corporation doesn't want its editors to go wild with blocks and widgets in their posts and pages. An agency doesn't want the client to play designer and go crazy with the theme customisation. They're features meant for the Squarespace/Wix market, and not ones that necessarily fit something like WordPress. But eh, it feels like there's too much focus on trying to compete with page builders and hosted site building tools, and not enough focus on fleshing out the features already included there, or providing a solid, easily extendable editing experience for existing WordPress site owners.
