How to start a project (Nuxt 3, Composition API, MongoDB.)

First of all sorry about this question, sounds extremly basic, but I spent the whole day trying different things and I don't have a good outcome. I need to learn how to get this: A Nuxt 3 app with the Composition API connected to MongoDB. I've been doing SvelteKit and Next.js and I quite like this SSR when we do all this backend work, but there are so many ways to do it that I get dizzy: compostables, server directory... Any repo I could research or tutorial, any advice, I just feel a bit lost, and I burnt the AI, I need some humans. Thanks.
