Some might find React a boring choice in 2022, but I've never been so productive with it. It still has the best ecosystem of libraries and its flexibility makes it suitable for any project. I usually use it together with a metaframework such as Remix, Next or Astro.

Node is very mature and an excellent backend runtime for most projects. Besides having a great community behind, being able to use TypeScript for your backend and your frontend is key for productiviy.

Despite its flaws, Electron has enabled many small companies to develop cross-platform desktop applications using web technologies. I also like Tauri, that addresses many of Electron's issues.

It's hard to go wrong with Postgres. Works great paired with Prisma to have type safety.

MongoDB is great for problems that are not suited for the relational model, flexible and scalable.
