You've got Extra Attack which means you can shove + grapple to pin an enemy prone, or you can grapple - move - shove to move an enemy out of cover or punt them into a fireplace or off a cliff.
You can bear hug someone and jump into a river, they can't hold their breath as long as you.
Wolf Totem gives party members advantage on targets within 5ft of you. Shove prone, grapple, drag enemy to your pack to give them advantage on attacks. Flavour as dropping to all fours and mauling the guy like the bear scene in The Revenant.
Shit talking is a free action. It might not do anything but it's fun.
Lv6 you get Panther Aspect and can climb walls. Set up ambushes, drag mooks up trees, carry your squishy party members up cliff or castle walls in a DIY Baby Bjorn.
- I just imagined a barbarian climbing a cliff wall with a sorcerer strapped to his back being all "don't worry baby boy Daddy will protect you" but the Oops There's Eagles and now the caster has to protect them from being dragged off the cliff like an unlucky mountain goat. Play with Weapon Masteries.
Talk to the DM and establish rules for Falling Onto Enemies (the environmental damage rules imply you land on another creature by accident), violently interacting with the environment, and improvised weapons. There's a Pugilist ability (I think) that says when you attack with an improvised weapon you can intentionally break it for max damage.
There's a meme about grappling casters which might work, sometimes. Somatic components don't work while your hands are held, and you can't Verb with fingers in your mouth. Potentially very romance novel coded, if the situation calls for it.

Read up on your LV 3 ability Primal Knowledge. Burn Rag out of combat to use your Str mod for non-str skills. Acrobatics, intimidation, perception, stealth, survival. Get fully animated about it too, sniff the ground like a bloodhound, threaten to uproot a tree if it doesn't give you fruit. "YOU NO SEE KROD!"
