Python/Django and Elixir/Phoenix are both excellent. Which of these 2 is preferable should be, IMO, dependent on where you are in the development process.

Personally, if I was joining a team with a mature codebase, a decent auth system already built, and UI for for of the relevant models, I would prefer Elixir/Phoenix because I like and believe in pragmatic Functional Programming and the potential for concurrency and scalability built into the BEAM runtime. Phoenix LiveView really is amazing.

In your case, though, you’re talking about building an MVP, and Django’s model, auth, and admin layers are top-notch and integrate effortlessly. Outside of core Django, there’s an ecosystem of third-party packages for virtually everything you might possibly need.

Whichever route you go, for an MVP I highly recommend skipping the JSON API coupled with an SPA (React, Vue, etc.) approach. Use Phoenix with LiveView or Django with either htmx (preferred, see it over at https://htmx.org) or Hotwire (https://hotwired.dev).
