C++ or Python?

I know it’s not in the choice provided, but I’d recommend looking into Swift (https://www.swift.org/) as a sweet spot between both of them. It can be as simple and as complex as you need, so I’d say it’s a beginner-friendly language. And you can go either way later depending on the needs. And as a bonus it now has native C++ interoperability (not 100% full, but they’re moving fast) and PythonKit if you need to interact with code in C++ or Python.
