There’s a huge need for this, thank you! I build server-rendered marketing sites and there’s a huge gulf between the jQuery and React era.
I think you can get quite far these days WITHOUT React or Vue.js (and I say that as the maintainer of a Next.js/React open source project [1]).

There are not sets of polished, battle-tested UI libraries made for server side. Bootstrap ships with JS, but most of the CSS and template frameworks assume you’re using a headless setup.
I thought Web Components might spur things, but not really. React has continued to dominate.
