I don't advocate use of urine for folks on persistent medications and the like, but otherwise the guidelines I use are pretty basic:

Direct use is fine for plants not being used for consumption, or for trees and shrubs where the food portion is off the ground and away from splash back. If they're where others can see you it might be better to use a container to be more discreet.

Anything else will get a helping of the homemade compost with homemade charcoal that's been used to sequester the nutrients (also homemade).

Iirc many of the contaminants will be salts which will get flushed with irrigation or precipitation, but folks can also just dilute urea with water 10:1 or more to reduce the likelihood of salt buildup in the soil
