There are at least a few CMS editors for static sites intended for non-technical/less-technical users. They often still require someone technical to setup (config files and OAuth connections to GitHub, for example) but then provide an experience somewhat like what one would expect from the WordPress Admin Page.

Two examples I've briefly worked with:

Decap CMS (formerly Netlify CMS): https://decapcms.org/

Lume CMS: https://lume.land/cms/
