Besides Vulcans and Denobulans, what races had Humans encountered before "Broken Bow"?

I kind of assumed the Vulcan-only crews in TOS weren't unique, and that each Federation planet would have ships like that, for whatever reason.

So, context..
How many have they actively gone out to there home planet, or seen them about on there cargo runs, etc. or those that have come by earth to see the new kid in town??

Vulcans?

Vulcans seem quite insular.

And by the 24th century, the Federation have Vulcan only crews.

There was a ship with an all vulcan crew in TOS. Spock mentioned it once.

The Intrepid, which was killed by the amoeba thing. https://memory-alpha.fandom.com/wiki/USS_Intrepid_(NCC-1631)

Just further reinforces that Vulcans have managed to keep it secret for a very long time. 100+ years of Vulcan-only Federation crews.

Sure, all “Vulcan”.

clearly it was a Romulan spy ship having infiltrated Starfleet.
