Why not use notion and their website feature with custom domain? It has an extension to clip pages as bookmarks.

You could add it as a subdomain (bookmarks.website.com)

It’s easier to update compared to hosting your own CMS and frontend.

SSG are indeed a perfect fit for this. But you do need to figure out a few things like search (client side), RSS, and how to organize things. I didn't want to maintain a dedicated backend for my blog and integrated a link blog to my static site. Wrote about it here:

Simon's site runs on Django: https://github.com/simonw/simonwillisonblog, which is unsurprising as he is one of Django's co-creators.

But I agree with you, a great use case for a Next.js-esque static site.
