Other than the obvious moral boundaries, there two main categories of things I refuse to do. There are beverages I refuse to drink and jobs I refuse to do.

Beverages

Despite being willing to eat most foods, I drink a very small variety of beverages. I do not drink anything containing alcohol, caffeine, carbonation, or corn syrup. On most days I drink water exclusively. On special occasions I will drink juice that is entirely made with real fruit, a lemonate, or dairy beverages such as milk shake or lassi.

Jobs

If I were to be in a difficult financial situation I might have to accept employment I do not approve of for the sake of survival. As long as that is not the case I will refuse to work in the industries of finance, cryptocurrency, defense, for-profit medicine, big tech, or at any place that is high on LLMs.
