If you are already committed to Python for the data analysis then it would make sense to use Django for the framework and stick with Python throughout. In general the fewer technologies you use (unless there is real justification) will improve process and long term costs.

All things being equal the fact you would not have less (likely no) licensing costs with a Python based solution will overall reduce your long term costs.

RingCentral is reselling Zoom. Given the security issues with Zoom lately, and how aggressively they have been updating the platform to be more secure, I am not comfortable using RingCentral for anything private.

For example, as of a few weeks ago, Zoom had updated their app about 6 times since December. At least some of those updates had significant security updates. Where a Ring Central had no updates between that timeframe.

With RingCentral you are getting an older version of Zoom. If the newer Zoom features and privacy are not a priority; and RingCentral is offering materially better pricing I might consider them.
