I think it's just a matter of RP/personal preference.
Because the Echo gives us (as the single-player) the ability to understand all languages, we never really see if it's a result of everyone speaking a common tongue of if our characters just happen to be fluent in everything.
There's a gradient of people who RP between [everyone speaks the same thing all the time and everywhere] <-> [Each race/nation has its own language, or had its own language once]
Personally, I like to think that some nations have certain other languages. Like Ishgard, Garlemald and Doma. And I'd imagine some Sea Wolves might possibly practice their old language. Miqo'te as well.
