If you choose Psalm 80:1-8 then you should include the square bracketed verses from Luke, so the Magnificat is included whichever way you do things.
Micah 5:2-5a is a prophecy about one who will come from Bethlehem to restore his people and care for them as a shepherd cares for his flock.
Luke 1:46-55 is the Magnificat.
Psalm 80:1-8 is a prayer for the restoration of Israel. “Turn us again, Lord God of hosts”.
Hebrews 10:5-10 is about the sacrifice of Jesus being the will of God, rather than the Temple sacrifices that were offered according to the Law.
Luke 1:39-55 is Mary’s visit to her cousin Elizabeth.
