What size category of prey did Xiongguanlong target based on its stature?

Answer

Smaller dinosaurs and other small animals

Due to its medium size of approximately 4.3 meters, Xiongguanlong's prey spectrum was calibrated to target smaller dinosaurs and various other small animals prevalent in its Early Cretaceous habitat. This prey spectrum, which might include early ornithopods or smaller ornithischians, is perfectly commensurate with a predator of its stature. Such prey selection allowed it to avoid direct competition with much larger theropods whose caloric requirements necessitated targeting significantly larger meals.
