Cherubim are mighty angels. That God is "enthroned above the cherubim" is a reminder of his presence on the Ark of the Covenant (Exo 25:17-22).
Psalms 80:3
Twice the writer calls on God to "turn us again to yourself." Before God can turn us to himself, we must turn away from sin. Repentance involves humbling ourselves and turning to God to receive his forgiveness. As we turn to God, he helps us see ourselves, including our sin, more clearly. Then, as we see our sin, we must repeat the process of repentance. Only then can we constantly be restored to fellowship with God.
Psalms 80:7

Psalms 80:17
"The son of your choice" is probably not the Messiah but Israel, whom God calls elsewhere his "firstborn son" (Exo 4:22). The psalm writer is making a plea that God would restore his mercy to Israel, the people he chose to bring his message into the world.
