Battle smith seems like a solid choice. Max Int, maybe Dungeon Delver? Skills, defense, utility, decent damage.

Other ideas:
Barbarian totem warrior (bear totem). High Con, maybe Shield Master? Can smash and doesn't die easily.

Moon druid. Can scout with ablative wild shape "armor". Spellcasting. You don't really need high stats, so room for more feats. Prodigy (Perception expertise) + Observant + Enhance Ability spell = no surprises.
