If you head north of your spawn, you will find a decent sized village. In the village there is a cave where there is a pumpkin and a spider spawner.
The best thing about this cave is the spiders can’t leave because of the shape of the cave so it’s easy to farm by just standing in front and hitting them at the entrance.
If you head west from the center of the village, you will find a zombie cage spawner.
Finally, if you head east towards the swamp, you will encounter a witch hut.
