First off, that seems like a pretty solid draft. That being said, you might want to give the following some thought -

1. Build the frontend in Next.js and use rest calls to a separate api server.
2. Use Nest.js to create your api layer. It supports Prisma and is a really mature framework.
3. If most of your apps functionality is auth walled (ie. users need to be logged in to see the pages) you might find Remix interesting as it gives you a must more performant alternative to Next.js for the frontend.
