I think WordPress has strayed from its roots as a blogging platform. Automattic seems interested in building a content management system to compete with Medium and Wix. I've used WordPress since 2003. I have an intense dislike of Gutenberg. Hopefully, I will have time this weekend to learn more about ClassicPress.
I don't have much to add to the discussion but wanted to voice my dissatisfaction with Gutenberg and how it disrupts my recently discovered IndieWeb power (Webmentions). I considered switching to Jekyll, Hugo or Grav but ran into challenges migrating over 15 years of content and several thousand posts.
There is a fork, ClassicPress, already. I may spin up a VPS this weekend and try it out.
