I personally wanted to use docuensarus, but since I'm more in infrastructure and not in development, I found mkdocs with mkdocs-material to just be easier to use.
The only thing I can see is that maybe you are more familiar with Python than Node.js? Otherwise using Docusaurus or MkDocs are both equally easy IMHO
You can get a Docusaurus site online in 1 minute, and publish your first doc edit in 2 minutes. See demo video: https://twitter.com/leeerob/status/1554211061284364290
You can even try it in your browser right now: https://docusaurus.new
I didn't need any coding.
The only difference is that our config file is a .js file instead of .yaml, which I'd say is more powerful since you can do fancy things like reading env variables to make your config "dynamic".
But by default a Docusaurus config file is not too complex. Probably a bit more than MkDocs (as we keep some boilerplate on purpose so that you can just tweak it) but still not really requiring to be a JS developer to edit. See: https://github.com/facebook/docusaurus/blob/main/examples/cl...
