There are various tools for creating software documentation; some of the popular ones are GitHub, Read The Docs, Docz, Docusaurus, Dropbox Paper, Documize, etc. You can use whichever tool you feel comfortable with, having in mind that they all have their ups and downs.

The Documize Community Github description states that content PDF export is a feature of the Community+ edition, which is available for download on their download page here as opposed to the Github release builds. If you indeed have more than 10 users, then you can't use Community+, so you won't have the ability to natively export content as PDF.

Material Mk-Docs by Martin Donath works well if you prefer python.

I'm an 'outsider', but from from the outside the Material For MkDocs Project looks like a very well managed open source project.

Martin Donath's project uses a 'sponsorware' release strategy to generate donations.

From my vantage point it seems to be working pretty well.

I just recently went through this decision process. My aim is to write code and math oriented posts so I need good support for nice syntax highlighting (at least colored) and mathjax (preferable) or katex. Substack is the most popular newsletter platform but fails at these two criteria. I love how math and syntax highlighting (plus numerous other features) work in MkDocs Material, which recently added a Blog plugin.

I wanted to combine the best of both: Substack as an amazing email social network, and MkDocs Material’s awesome look. So I’ve gone with using Substack as the core platform which I use to manage subscribers, and use it to post either math/code-free posts or a short teasers pointing to my main blog site on MkDocs Material when I need to show math/code

I've been migrating content to MKDocs (Material) over the last few months, so feel fairly qualified on this subject. It's somewhat limited in terms of navigation, but can probably handle 400-500 pages; you can see how navigation works in the link. Otherwise, it can handle most, if not all, the tasks you've listed.
