Looking for a fresh seed and found this bedrock post. Works pretty well for Java too, even with all the updates.
The only two structures not on the main continent are a Desert Temple and a Stronghold. Closest Desert Temple is only 1500 blocks from spawn and the Closest Stronghold is only 2000 blocks from spawn. (I also love that it has all 5 village types)
A few niche biomes are missing from "The Continent" (Flower Forest, Sunflower Plains, Ice Spikes, Savanna Plateau, Gravelly Hills) but are still relatively close ~3000 blocks.
The only biomes that look like they are effectively missing from the spawn area (3000 block radius) are Snowy Slopes and Jagged Peaks.
