Sorry I should have linked to their main site that does a better job of explaining rather than the GitHub: https://anchorcms.com/Nice, I didn't know that one. Will look into it.
It's PHP/MySQL based so will work on any basic hosting and it has an installer script so it's as simple as dropping on to FTP and visiting the installer link to fill in your info.
I still maintain that WordPress.com (and if you need more in future, WordPress.org) seems to meet your requirements except not being WordPress. WordPress.com has an enormous network of bloggers happily typing away without any thought behind the technology. But I used to run my blog on Anchor before moving to WordPress, it was nice, I just preferred a little more functionality that WP offered (the new Gutenberg editor in particular).
