Different stacks for different people. I prototyped an app with a MERN stack. Mongo, Express, React (CRA) and Node. By no means was the backend performant, and for this app, I had no reason to use document database instead of relational, but because I know how to write with mongoose, I chose mongodb. Now that the prototype is done, I'm looking at other languages and frameworks for the backend such as Phoenix, Hyper.rs or asp.net core. If I want to be lazy, I'll just convert the mongo queries to Postgres and be done with it, and then move my CRA React App to Next.JS.
