Update: I did all of the steps above. Killing the dragon was the hardest part, I just spawn-camped and pillared up to destroy the end crystals, and then used beds and the sword to finish it up. It took me 3 hours to beat the dragon, but since this is no speedrun I also have wheat, carrot, potato, sugarcane, and beetroot farms going, and I have a mending villager as well. I have a “temporary nether hub” and a blaze farm as well, and basically infinite XP and ender pearls thanks to the end.
I’ll send some screenshots once I have a base that isn’t an abomination of a desert village hut.
