A quick search on D&D Beyond suggests the following spells.
Cantrips:
- Acid Splash (?)
- Sacred Flame
1st level:
- Catapult
- Hellish Rebuke
2nd level:
- Cordon of Arrows
4th level:
- Grasping Vine
- Guardian of Faith
- Otiluke's Resilient Sphere
5th level:
- Enervation
- Immolation
6th level:
- Disintegrate
I basically ignored anything with an AoE, even if it was a 5' cube. Acid Splash can target one or two creatures, so Shield Master would only apply if there was a single target.
Edit: Yeah, reading through Catapult more closely suggests that should probably be on the list, since it stops after it hits a target.
