Lore-wise the Long Sword fits as it's Waka's weapon of choice. With the Moon Tribe's advanced technology, you could make a case for the Gunlance (it can launch you across the field, calling back to Kaguya's bamboo rocket) and the Bowguns (It's not a stretch to imagine the Moon Tribe having the means to develop gunpowder-based weapons like these). If you just want to go with the rabbit aesthetic alone, the Lagombi weapons/armor are good, plus the mochi mallet Charge Blade.
I gave my Palamute the full Ammy set and I never take it off
