Also in general, I would start with a list of languages that are built-for, or can easily support, what your product is. For instance, I love Go but wouldn't use it for a GUI application.
And in honesty, managed languages are a bit better in my opinion for projects that will require many devs to work on it. As much as this statement might catch flack, C++ is wonderful and powerful and I trust my ability to use it; but do I trust the workforce to? It's very easy for a dev to write a patch fix that also manages to introduce a memory leak or null pointer and crash the whole thing.
Unless you have tons of money you should avoid niche technologies/frameworks/languages. Solid choices include Ruby, Elixir, Python, Kotlin, Java. On frontend Typescript with React/Angular/Vue.
Technology is a secondary choice anyway. Most important is to find great engineers. These would naturally gravitate towards better tools anyway.
