If anybody cares, I made a guide to getting the perfect sword and bow. First I will go over then enchantments and then how to get a weapon with them.
Netherite Sword enchantments:
Mending
Unbreaking III
Sharpness V (Rather than Smite or BOA because it affects all mobs)
Fire Aspect II
Knockback II
Looting III
Use the following also if you have Java edition(exclusive):
Sweeping Edge III
Bow Enchantments:
Infinity (rather than mending because new bows are easy to make)
Unbreaking III
Flame
Punch II
Power V
The best way to get these on a weapon is to use books. You can enchant books at an enchanting table.
To combine books (and weapons), you need an anvil. Always put the book with more enchantments on it in the first slot, as it will cost less.
You can also enchant the weapon (using enchanting table) once to get a boost also.
If anybody wants, I'll make one of these for armor, tridents, etc.
