Forgot to mention Shocking Grasp, if I remember correctly this is a touch attack and doesn't get disadvantage on attack rolls like ranged spell attacks in melee. According to D&D RAW it should in fact give you advantage vs anyone using metal armor (dunno if implemented like that in BG3 though). Could be an alternative if you have nowhere to run with your Wizard at lower levels.
As for Warlock, levels 1-4 in Baldur's Gate 3 feels pretty good and If Hex is streamlined it'll be even better. The sound and animation for Eldritch Blast doesn't get annoying, which is critical to keeping Eldritch Blast fun.
Praying for that streamlining (want the curse secondary effect to be automated), or I likely won't consider Warlock as an option for my protagonist.
