Of course there are plenty of static site generators that will help with that.
For (internal) web applications, frameworks still win, because the difficult part isn't layout rendering, but the dynamic interactions on the screen. I don't think reloading the whole page on every click, even if it's super fast, is the way to go.
Blog content in particular. It amazes me that anyone actually uses the likes of Wordpress day to day.
Want to have some interesting facts, links, images, etc. in a sidebar, but only for some pages, etc.? The static site generator goes up in flames or needs a lot of manual tweaking. In WordPress and any other CMS it's either built-in or one plugin install away.
Want to edit some published page, create and preview something new? With SSG you need to make sure you have the latest version locally, then edit the file, create a new commit or copy the file, push the change, wait for some pipeline to run and only then will you see the actual result.
Don't get me wrong SSG are great, but they are solutions for very technical people who like to fiddle with workflows and automations. If you want a WYSIWYG and one-click install experience, you end up with some CMS.
And that hasn't even touched the whole web shop integration topic.
