Since you mentioned being a juggernaut, I recommend a few levels in Fighter with the Siegebreaker archetype, and the Charge Through and Spiked Destroyer feats. They combo nicely at bashing through enemies.

Also, consider one level of anything that can take the Plant domain (cleric, druid, inquisitor, ...) so you can enlarge yourself as a swift.

And if you're a dwarf, take the Steel Soul feat.
