Struggling to pick a job..

Going from tank I would have to recommend a melee job as these are at closest to what you're currently used to. I think playing from a melee perspective helps you understand what a good tank is, and when/if you ever go back to tanking that experience as a melee will help you be a better tank. Playing as a ranged is a lot different than playing as a melee/tank. Being able to move while you execute attacks is one of the biggest conveniences on the melee classes, getting out of that habit is kinda tough, but not impossible if you're looking for a total change of pace.

NIN is probably the best support melee if you are looking for more utility, followed by DRG. Both DRG and MNK are very competitive in damage, NIN is a little behind in that regard but offers more raid utility than either MNK or DRG as Morzy's overview explains.
