Spawn on the edge of a plain where it meets both desert and forest. A few steps north is a cave entrance with a dungeon with zombie spawner. The cave has lots of visible coal and iron ore.
Just to the north of that is a desert village.
There are loads of sheep so you can make a bed first day.
A few steps to the west is a savanna biome.
Several ocean monuments not too far away, and lots of sand in the deserts for draining them.
There are several surface lava pools nearby if you want to use the mold pouring method of building a portal. Once through the portal there is a big cluster of glowstone within reach, and a nether fortress a couple hundred blocks north-west.
