Multiclassing Shadow Sorcerer

Hiya, I'm currently a lv 6 Dhampir -noble shadow sorcerer. We've just leveled up and im stuck between multiclassing into gloomstalker or hexblade. I want my Dhampir to end up as a character that causes massive ranged damage but is punishing if someone gets up close. So far she's pretty good on the ranged damage (near soled a god last session) but I'm always down for improvement. Her melee was decent and her DC is 12, she has shield to move it up to 17. Any suggestions?
