Need help deciding on classes

Starting a new character. Doing a Jedi Knight playthrough thats gonna go through, RP as a Qui-Gon/Anakin combination jedi. Like if Qui Gon fought with a lot of aggression, but conducted himself like a Jedi if that makes sense. I was thinking of doing a Juggernaut Jedi Knight, but I also kinda wanna try something new. Specifically, I always play as Jug/Guardian, Assassin/Shadow, or Sage/Sorcerer. Ive never done a Marauder, but I dont know if that'll really fit the whole "controlled rage" gameplay feel. Plus, if I did that, what should my secondary class be? Shadow is always nice with stealth, but Sage has a lot of AOE damage and healing specs.
