Copy it into Minecraft 26.3 (Java).

You start in a Grove at y=125, and Frozen Peaks sit only about 64 blocks away, which makes this a ready-made mountain base. Forest and Old Growth Birch Forest lie at the same distance, so wood is easy. A Ruined Portal waits about 88 blocks south, and an Ancient City lies about 336 blocks west of spawn. The Ocean Monument is a longer trip, about 943 blocks west.
