Do you have to use dynamic site generation?
Even if it is a blog with multiple authors, you can use static site generator such as Hugo, Jekyll and (my favourite) Pelican. Pelican also generates Atom/RSS feed for entire blog or for each tag.
@murtezayesil Thank you for suggesting this. It's a shopping site for a friend and I have enough time to look around for my options. Pelican probably doesn't work but I found this tutorial for Hugo https://snipcart.com/blog/hugo-tutorial-static-site-ecommerce and even though it ads some Google-stuff it looks easy to remove. Haven't researched the third parties used in that tutorial though. Hopefully there's something.
WordPress isn't bad if you can remove Google dependencies. But it can be overkill if store won't have so many items. @kev's blog uses WordPress and GTmetrix report shows no use of any Google service. If you really need WordPress, maybe he can help you get rid of Google.

If you’re using Google fonts on your theme, you will need to make a child theme and self-host the fonts you want to use. Here’s how:
