The headline here is the Ancient City, about 305 blocks north-east of spawn, which gives you deep-dark loot early. An Ocean Monument sits about 440 blocks south-west, and a Pillager Outpost lies about 341 blocks the same way. Spawn is in a Forest with a river and birch woods within about 100 blocks, so you can gear up before the trip. Plains, ocean and cold slopes fill out the rest of the map.
