I went with:
Terraformed AWS/EKS
Docker
Postgres
Node/Express
React
I'm pretty language agnostic, but for webstack I like to use Node, because it means I don't have to context switch too hard. I'm using the same language on the frontend and backend with the same APIs. I only have to keep one standard library in my head and a lot of packages are compatible with either front or backend.
Whenever I'm working on the web, that's going to be my go to.
I would consider Typescript, but I don't think the cost/benefit of Typescript really balances out until you have a team. The need to create types and type harnesses for libraries slows you down at first, and speed is the name of the game with an MVP.
