Wordpress.com is expensive if you want "advanced" features like editing the CSS(!). As for Blogger, I don't want to tie them to a proprietary solution.
Update: Maybe take a closer look to OctoberCMS. It seems to go into your direction.
Thanks for the suggestion, but it doesn't seem like it generates static pages...? I'm keen on that because I really don't want to have to babysit the server and apply security fixes (I trust nginx to auto-update without breaking the site).
Once you've got your content CMS-side, you can then pull that content into your SSG during the build process. All of those offerings I mentioned also have webhook support, so on publish of any content you can refire the build (to then pull down the new content).
We are loving this setup. There are really very few downsides.
