Play what you want, though I'd recommend playing either a face class or a barb first off.
Face classes for the obvious advantage on talking your way out of things. But barbs have a special interaction on the tutorial level that can help you snowball your party without the cost other classes face for the same option. And barbs tend to do good on intimidation checks so they can ki d of face too.
Barbarian is very good for combat, if you're struggling with combat in the game the barbarian can be a big help. But I don't find it a particularly interesting in a game with so many skill and proficiency checks. I plan to play one of the charisma spellcaster classes so I can have mastery in intimidation, persuasion, and deception, but I think ultimately the best classes for exploring all the wide narrative options of this game will be the skill monkeys.
