I would definitely go with Strapi as a backend for a project like that. It already as great features like user signup/login with various providers and has a proper permission management. I has a very good API that is easy to use and data can be accessed with GraphQL if needed. I found it easy to run locally for development and the deployment process can be really easy as well.

Supabase is also an alternative I have tried once but it had less features than Strapi when I tried it at the time

React is definitely a good choice for the front-end part. On the backend side, if you already know Django, you should keep it unless you have time to invest in Javascript backend like NestJS which is great
