I dunno how that posted twice...

In high school, I studied two languages that were supposed to be more "international" than English ~ not just Latin, but French as well. The notion that French was the essential language of international diplomacy was already a good half-century out of date back then, and of course by now it's an absolute joke.

Spanish would certainly be much more practical than either, certainly here in the Western Hemisphere, and the next-most-universal languages would have to be Japanese and Chinese.

Japanese is currently a bit more important for international commerce, but gazillions of Chinese will sooner or later make their presence felt on the World Wide Web and in the 3D world as well.
