Summary pretty much describes it; I tried applying the enchantment to a Netherite Hoe, but it said that enchantment is not supported on Netherite Hoes. Despite this, it works just fine on Diamond Hoes. All other enchantments seem to work fine on Netherite Hoes, just not Silk Touch.

EDIT: Didn't realize I had fortune on the hoe, nevermind!
