Lots of good suggestions here, but a lot of them are for complex development stacks. My criteria was something that can be installed and ran without having to do much wiring up. That being said I do love me an SSG and content API, my own site is Eleventy hooked up to Ghost.
Also saw some suggestions like Drupal and Joomla, I may add these but from personal experience I've almost always been migrating away from them. There's a reason they're popular though.
Ps. Sorry if you got upset about the political spin, but it's not escapable. Tech is not exempt from politics.
If you look at the various options being suggested in the comments here you'll see many of them don't come with comments out of the box. Jekyll, Gatsby, Hugo, 11ty all require you to use a third party service or roll your own.
You can have the best of both worlds though. You can use gulp.js to build Jekyll friendly files coming from Ghost using the Ghost Content API: https://david.darn.es/tutorial/2019/08/11/use-ghost-with-jek...
