tech-heresy GOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO
+1 to Cunning
I just can't find enough advantages to Venerable since it's so...not broadly useful and risks problems like "they remember the days before you conquered them" and "if they roll badly on tech then they don't have any useful information to share with you because they just straight up didn't notice anything cool going on in the galaxy".
I am tempted by allying with Yoda's species, but the possible benefits of cunning are hard to pass up.

Cunning is trusting the plan.
The Xenos are
Cunning, for all of their weakness, for all of their frailty, a mind beyond their meat swells and simmers, contemplating unknowable schemes and heresies within heresies. Fear the Xenos, not for its power, but for its works.
For all of the gifts that mother nature is willing to give its bastard, alien spawn, it is all to willing to take that and more away. The Xenos are lesser than mankind, this cannot be forgotten.

The Xenos are
Weak which should come as no suprise whatsoever, given their miniscule physiology. It's likely a human child could match or surpass an example of their kind in terms of sheer brawn. They will have to be useful in other ways than hard labour, although they can still do hard labour, only inefficiently and it's rather difficult to coerce them.

The Xenos are
Fragile, they might as well be made of glass for all of the resilience they show to trauma. How worthless is a will of the hardest steel if it should be housed in a vessel of wet clay? The Xenos are hardly worthy of your contempt, pity them, for they are not of Terra.
