As soon as you spawn, go straight forward from spawn, you will come to a Savanna Village but keep going past that. You will come to a large Shattered Savanna Plateau (the mountain) that is touching a Eroded Badlands! On the right side of the mountain is a Desert village running up the side and creating really cool ledges. Under one ledge in the village is an exposed Skeleton Dungeon! On the left side of the mountain, there is a Pillager Outpost in that Desert.
However, If you go straight behind spawn, you can find a really cool Shatter Savanna biome with very cool overhands and a crater-like pit full of sand. This could make a great place for a build! And lastly, if you go to the right from spawn for a bit, you can find a tree with a Beehive under it! See coordinates listed or the map for their exact locations.
