Starting a new campaign - wondering which class to pick!

Hey all

I've recently joined a new campaign for a module I've never tried before called Dungeon of the Mad Mage.. The DM told me that this is less like an open world adventure and more like a classic dungeon crawl. I've never played a campaign like that before. Way more centered around combat and navigating a dungeon designed to kill us than what I'm used to.

So far we have four people including me - a barbarian and a wizard. Not sure what the last guy is gonna play yet. What I'm having trouble with is which class (and subclass) to pick.

Rogue seems like a good pick since it's a dungeon and I expect it'll have many traps but I'm not sure yet. The new Monk, Bard and Cleric all seem pretty fun as well. Don't mind picking something other than those classes tho.

Any advice?

Edit: The Campaign starts at Lv 5
