Sveltekit is the fullstack/SSR version of svelte (like next is for react or nuxt is for vue). I reckon learning one of them might be helpful to learn component-based SSR and its benefits, personally I do think they have a firm place in the future of webapps.

Vite I can highly recommend, it's the best, fastest and least fussy bundler/builder I have ever used hands down (having used webpack briefly and packer for a while). Has some great features and is less of a pain to configure and get to work in my experience.
