In my experience, the problem with a lot of those solutions is that at some point you still need to handle data and some significant dynamic content. Of course, this depends on what you do, but even a simple e-commerce site is fairly dynamic nowadays.

What happens if you go the I'll-do-it-myself is that you still get a significant amount of code, and lots more bugs since you'll have to redevelop significant pieces of what the libraries and frameworks already have done (and tested) - and you'll ever be better than them.

Of course, you don't need to use Javascript to render your whole page. You can still use React or Vue to add these dynamic parts, and render the rest at the backend.

Imo this might be one of the most underrated ways of doing things. I guess human tend to go to the extremes without being rational about it necessarily (or thinking for themselves and just buying into the hype).
