It's a fairly unpopular opinion, but after more than 20 years of software development, leadership and management, I propose the following:

1. is there a KO argument against a particular technology?

For example, high performance trading development is quite different from many other use cases. You really need a fast technology. But for most use cases the concrete technology is irrelevant.

2. Follow your team's passion.

After removing technologies that are not appropriate, just use what you are passionate about. In my opinion, the team learns very quickly when they are passionate about something. Of course, experience also plays a role, but a motivated team is more important to me. And after use a new technology, the team becomes even more experienced.
