twin buffs, 3 attacks (4 with haste), than cast a spell (or booming blade) with the bonus action that the target/s will save with desadvantage and you still can subtract 1d4 from the result. plus wild magic is great in front line.
If you'll use only spells for buff, you can dump Cha and Int.
pali/sorc is great too. Auras are amazing, oath of ancients will protect you from wild magic, but you have less Asi/feat and no desadvantage in enemies saves (unless you burn 3 SP).
