It seems kind of regressive to have Starfleet Academy in ONE location

As fast as I can tell (unless there is an episode or expository dialouge I am missing), the Starfleet Academy for the UFoP is in the sole location of San Francisco, California.

I know it's kind of a running joke, that American stories have everything world changing happen in America, but it is kind of sad that a utopian vision of the future is still victim to the narrow lens of American Exceptionalism.

And I get the original series was written in the 60s during the height of the Space Race and Americans were exceptionally jigonistic around this time (ironic considering the social turmoil of that decade), but you'd think TNG or DS9 would expand upon Starfleet locations.

Maybe Palestine has a Starfleet Academy? Or North Korea? Or Rwanda? Or Bosnia?

What better way to showcase a post-tribal humanity than to show Starfleet Academies in some of the most geopolitical hotbeds in history.

On that note, it would be cool to see more Starfleet captains in crews comprised of different nationalities.

They do this sparingly throughout the franchise, but most of the major human players are almost always from America.
