Although I think it's not a big issue, I'd look into Vue instead of React. Imo it's simpler and give you a more complete solution out of the box (routing, reactive data layer).
Now, I've barely tested Django, but I would not go the python way unless you have a good (other) reason. Rails seems to have a much more developed web development community. Node might be a great choice due to you being able to use the same language (and libraries), but I'm a little bit disappointed by the ecosystem. The libraries and frameworks that exist does not seem as mature (and high quality) as in other ecosystems.
For backend, my experience with C# ASP.NET Core has been great. Visual Studio is great. C# is a really nice language to work with, and have quite mature and well-backed Lucy ecosystem. All in all it's pretty equal to Rails though.
I'd also recommend looking into Azure DevOps (or Gitlab) for a nice, full experience for DevOps.
