I would say, though, that for most programs any one of the most popular languages would do the trick. By this I mean Java, Go, C#. Javascript, Python, C++. All of those are general purpose multi-paradigm languages that you can code almost anything in.

That being said, some programs can only be written in one of those. Browser code is JS exclusive, low-level needs C++, secure code needs not C++. Machine Learning needs Python and high performance can't use Python. Some Windows things need C#. Those cases are the obvious ones where there is basically no choice. Beyond those, it is mostly about the team.

Which of course ignores and contradicts the primary lesson of the chap who founded this company and pays for this website.
