There's a certain canon-historical force that you haven't counted for. The Jaffa we see certainly in the first few seasons are all soldiers of the Egyptian/African gods (Ra, Horus, Apophis) so it would make complete sense for them to be of African extraction.
The samelogic would apply to "an Asiatic civilisation that's either run like the Japanese samurai", since it would have had a similar cultural genesis to Earth Japan, it's quite plausible it would have developed in the same way.
As the Goa'uld we've met have become more diverse, so have the jaffa
Both the Ethosians and the Satedans we've met have been of all races/colours/extractions, so I'd be inclined to say the casting of coloured actors in those roles was simply due to finding the best person for the job rather than having a pre-determined racial agenda.
"...but who don't even get a mention on the 'we could pick over their bones and see if they developed something we haven't' scale."
As you mention, they're getting to that. I think it's an ep they just didn't have time to do this year.
And while we're on the subject of pre-concieved ideas about groups of people...
"...all the people from up north completely turned around by the fact that the sun's path lies northwards and not south, while the people from the southern hemisphere are all "what are you guys going on about?" While secretly snickering behind their hands"
Just how dumb do you think people who live above the equator are? The sun moving in a contrary manner in the Southern hemisphere isn't that difficult a concept to grasp, or one that's going to leave us reeling if we're shown it on TV.
