What do these cities share in terms of racial demographics? Not a rhetorical question. They are all pretty much lily white. I wonder if that factors into their low unemployment rate.
Also note that 5 of these 10 cities are State capitols. They are well-employed not just because of universities but because of the expansion of government in those cities piggy-backing on school hiring. Since 2010, State government hiring has outpaced private sector hiring at near 3:1.

And you are correct about the racial makeup, although I don’t believe there is sufficient reason to relate racial makeup to low unemployment.
