Your Java 26.3 spawn is plain, standing in Plains at y=93, but the good stuff sits close. A Bamboo Jungle begins about 192 blocks out, with Sparse Jungle at about 128 and full Jungle at about 202. An Ancient City lies about 386 blocks north-west, and a Jungle Temple about 456 blocks south-west. Three villages fall within roughly 640 blocks, so early supplies are easy. The Woodland Mansion is a long trip, about 1086 blocks south-west.
