I would consider getting Shadow Blade at some point (like EK 8 or Bard 6). When you have someone grappled and prone, cast Shadow Blade and hit them twice for 2d8+Strength+1d4. it will outdistance Booming Blade over the course of a typical fight and you could still do Booming Blade with it. Plus you can throw it and summon it back as a bonus action if need be. And in Dim Light or Darkness you'll have advantage without knocking prone.
Summon that bad boy and Action Surge and you'll have a round full of laying hurt on someone.
