Weapons that are size Huge for a large creature taking the Giant Instinct

As the title suggests, my player is a Minotaur Barbarian taking the Giant Instinct which states “If you’re not Small or Medium, you can use a weapon built for a creature one size larger than you.”

The question is. Are there weapons with this size? I haven’t found any in the Nethys Archives besides siege weapons. Do I just scale other weapons to be bigger? Do I have to homebrew them?

Now I want to state. This is will be first time running PF2e. I have run other systems but not this one so any advice would be appreciated, thank you!
