The only other benifit of Next.js other than SEO is the project architecture that it provides.

If you are building web apps that live behind auth, it's a no brainer to use CSR. It's easy to deploy, cheaper to host and serve, not harder than SSR to develop. The cons about performance can be solved using code splitting. Moreover with proper caching, the app loads instantly.

Are there new age alternative CRA that provides a scalable project architecture like Next.js provides. Maybe it can come with basic libraries like react-router, react-query, pre installed and Vite pre configured.
