He's pretty decent as a Bruiser/Off-Tank/Full Tank. Depending on Top Lane matchup he can be quite dominant there, or as a Jungler. To the best of my knowledge he's considered quite strong at the moment because of Challenging Smite Cinderhulk which increases your Bonus HP by 25% which interacts well with his W.
If you're looking to build him as a Full-Tank Jungler, I'd suggest something along the lines of:

Full-Tank Top Lane:

Bruiser/Off-Tank:

VERY SITUATIONAL Challenging Smite Cinderhulk Top:

Challenging Smite Cinderhulk can be a bit risky in lane depending on what you're up against because you don't have Flash, but once you get your Bami's Cinder the lane becomes a lot easier.
Not going Righteous Glory as a Volibear Jungle is an awful idea. You need it to engage fights mid to late game. It is such a perfect item for Volibear that you can just ignore Frozen Heart for something else because of the Mana and get Thornmail for pure Armor instead.
Honestly, Ravenous is bad on him. Trinity is alright, but Iceborne or even Cleaver would be better options.
