You're kidding right? A programming language is another tech tool in the box. Just like using git, a debugger, Linux, nginx, etc.

Do you have different people in your team: one focused on nginx, one on bash, one on Python, one on PHP, and one on algo design?

A preferred domain perhaps. But a preferred language? That smells of sticking to one's (tightly drawn) comfort zone.

Preferences are usually a matter of personal opinion. They don't actually need to be justified.

I prefer to speak English. Yes, "language is arbitrary", but pointing that out is kind of missing the point, isn't it?
