My suggestion: Pick a cantrip that requires a saving throw. That gives you more versatility (and also doesn't give you disadvantage in melee). If you're facing an enemy with high AC, switching to a save-or-damage cantrip could be very effective. If not, lobbing javelins will do you fine.
If using XGtE, toll the dead is an obvious pick.
