Age-old questions. The traditional response is the concept of free choice. Suffering does not stem from the creation, but from the choice of the created beings. Why couldn’t have God have created things so there wouldn’t be suffering resulting from choice? Because then people would have just been automatons, little machines without free will, and not “in the image of God.”
(Traditionally, suffering is not seen as incompatible with benevolence: He who loveth, chastiseth" was a favorite bible verse among 19th-century disciplinarians.)

If I want to get in shape, I have to exercise and discipline myself. A certain amount of suffering is necessary and a good thing, too. Response: You tell that to the birds who are pushed out of the nests and eaten. They don’t prosper for their pain and suffering. Reply to that: In evolutionary terms it is not the individual who is the player but the species or genome. Perhaps the individual bird suffers & dies, but from the perspective of the species this is useful and beneficial suffering.
