Minecraft wiki entry for Defeating_a_Nether_fortress, associated text: For enchantments, Power is always useful, along with Unbreaking. Infinity is good although not required, Punch will have little effect since most mobs you shoot at will be far enough away for a slight amount of knockback to have no effect, and Flame has little to no effect except against a few mobs like piglins, hoglins and normal skeletons.
