Minecraft wiki entry for Defeating_a_pillager_outpost, associated text: It's possible to go around with a ranged weapon and pick off all the pillagers from afar. If using a crossbow, don't fire fireworks unless you're sure the fuse time is right and you're firing at a large group. Once the coast is clear, go in the outpost, deal with any pillagers inside, kill the outpost captain if you haven't already, and collect your loot. This tactic takes the longest.
