Can't you just use Wix or Wordpress or Squarespace or Medium, etc.? Otherwise, Astro makes it easy to self-host a blog written in Markdown, and Markdown WYSIWYGs you can easily get for your operating system. There are also older generators like Hugo and Jekyll, etc., but they've fallen out of fashion. You can also consider headless CMS systems (disclaimer: I work for one) but I think that's kinda overkill for what you need.
