Ask HN: Web app stack from scratch what technologies would you choose?

Hey there, I am doing research into choosing a productive technology stack for a new product. It's a web application.

I have mostly been doing go microservices and react UIs but the complexity of microservices and writing our own code for things that are not in our core domain such as identity/authn/authz or writing code for various communication layers just to do simple CRUD makes development very slow and expensive.

So what would you choose for a modern productive web app stack?
