I keep getting an itch to put together a centaur character for Missions play, but the hurdle of Uncouth, Uneducated, and deltaware-only puts such a crimp, that I wonder if there are builds that are worth the downsides?

Adept Centaur gets around the Cybernetics bit.

As for the other two, well, you're a fresh off the NAN plains where all the people you've known only your own tribe.    How else would one act?

One thing to remember is that both Uncouth and Uneducated can be bought off during character creation if you so choose.  Centaurs really don't have a lot of advantages - only two Attributes get a +1 boost, and they don't have much in the way of special abilities, either.  And with how incredibly distinctive they are, they won't be very practical for most campaigns.  I am not that well-informed about Missions play, but it seems to be "traditional" shadowrun.  A centaur would be better for a campaign set in a semi-wilderness setting (NAN, smugglers, paracritter hunters, etc.).  Their main ability is their Search power, so combine that with the Outdoor skill group and you can have a decent bounty hunter or guide.  Even so, you will be behind the power curve of the other players.  Centaur is a choice that is very sub-optimal from a numbers-crunching POV.

That's pretty much been my stumbling block, Glyph. Standing out can be forgiven for a character sufficiently good at what they do. Back to the drawing board I go!
