If they need metals they have nearly unlimited asteroids to mine. We have nothing to offer them that they don't have an overabundance of, aside from genetic material they can use for experiments but most likely they create synthetic life and it's irrelevant. The UFOs themselves would be piloted by AI and could be projecting holograms of entities that we can feel, and it doesn't need anything material.

Also, in Star Wars films the Galactic Empire corresponds to a Type III Kardashev civilization, if they take over living planets it is among themselves for logistical reasons not for resources. And most can identify with the human characters that have a stake in such affairs, however we correspond to the Type 0 Ewoks of Endor and are relatively insignificant to rest of the galaxy's inhabitants.
