Django vs Meteor vs Rails

Hi Community! Trust everyone is keeping safe. I am exploring the idea of building a #Neobank (App) with end-to-end banking capabilities. In the process of exploring this space, I have come across multiple Apps (N26, Revolut, Monese, etc) and explored their stacks in detail. The confusion remains to be the Backend Tech to be used?

What would you go with considering all of the languages such as Node.js Java Rails Python are suggested by some person or the other. As a general trend, I have noticed the usage of Node with React on the front or Node with a combination of Kotlin and Swift. Please suggest what would be the right approach!

As a small team, we wanted to pick the framework which allowed us to move quickly. There's no option better than Rails. Not having to solve the fundamentals means we can more quickly build our feature set. No other framework can beat ActiveRecord in terms of integration & ease-of use. To top it all of, there's a lot of attention paid to security in the framework, making almost everything safe-by-default.

Which is better to learn first as a beginner? Is it true that django is going out of the trend?

I was thinking to learn nodejs but after some thoughts I moved to django and learned most of the basics. Should I learn django more deeply or else drop the django learning and start learning nodejs from scratch?

Please help.
