Neither Vorta or Jem'Hadar showed any signs of interest in others romantically because their entire method of reproducing was cloning so romance was redundant, Weyoun specifically mentions his shit eyesight is because the Founders decided the Vorta don't need it, which they don't. They're not soldiers, they don't need perfect vision for spotting things and shooting other things. They did have incredible hearing and a resilience to toxins which helped immeasurably in their role as diplomats. DS9 just had more sense than modern shows, and Trek, back then despite the inherent woke slant a lot of the episodes would still add such as the form Dax and Khan hosts meaning the lesbian kiss between Jadzia and Lenara.
That's what Mass Effect did with the Shadow Broker from ME2, a Yahg with 8 eyes possessing "unrivaled perceptiveness and mental adaptability".
The yahg evolved to fill the niche of apex predator on Parnack. Yahg have four pairs of eyes, each pair designed to track and predict the movements of prey. A keen sensitivity to movement and light allows the yahg to easily read the body language of any species, making it almost impossible to lie to a yahg.
They don't play well with others, however.
When Parnack was discovered by Citadel Council surveyors in 2125 CE, the yahg were a pre-spaceflight civilization with technology equivalent to that of 20th century Earth. A Council delegation of ambassadors made first contact with the yahg and attempted to establish diplomatic relations. Unfortunately, the yahg perceived the ambassadors' attitudes and behavior as equal individuals instead of subordinates as a sign of contempt, and attacked and massacred the entire delegation. Immediately following that incident, the Citadel Council severed all contact with the yahg and declared Parnack off-limits. The Council maintains that the yahg's aggression and obsession with control make them poorly suited to integrate with the galactic community.

It's good flavor, but being able to read minute changes in the faces and body language of others would be huge boon to a diplomat.
