distributor VS Pico

You might look at the Distributor plugin from 10up, which syndicates content between different WP installs.

This is a solid option https://distributorplugin.com/

Might be interesting to compare what you came up with to the existing 10up solution

10up's Distributor plugin might be what you're looking for, although I haven't tried it with pages and posts created and edited with Elementor. Their WP Snapshots plugin might also prove useful.

I'm cooking up a really cheap publishing solution using Pico CMS ("stupidly simple") and rsync or something from my Obsidian Vault to my PHP server.

I'm using https://picocms.org/.

It is PHP based, works on a cheap limited web hoster.

The concept is: Upload a markdown file plus associated media, and it does the rest for you.

For customisation, you can use Twig and CSS, or a predefined theme (I didn't look into these, I wanted a custom appearance).

For feeds there are plugins, for comments I use a "mail me at [email protected]" approach.

I like PicoCMS a lot.

Have you tried Pico? No database required and. You can either use Markdown or plain text for posting. Each post is just a file... https://picocms.org/

Ever since version 2.0, Les Pas has been able to share albums with other Nextcloud users, you can even co-edit the same album with others if you publish the album as 'Joint Album'. But how about people not in your Nextcloud server, like those friends who attended your wedding? Create temporary guest accounts for them is just not feasible. Photo blog is here to help! And luckily, we have Pico, the stupidly simple & blazing fast, flat file CMS, which happens to have a very good Nextcloud [app]((https://apps.nextcloud.com/apps/cms_pico), enable us to publish our own blogs.

You can try Pico CMS. But if you have the time, try Hugo. The latter has a learning curve, and the docs are frustratingly non-beginner friendly, but once you get the basics, there is no going back!

Pico

For a blog, Pico can do the trick, and it's really handy to use (it uses Twig as template engine that's one of the best part for me).
