I remember a seed like this but it wasnt quite what I was looking for
1 tree survival island seed, huge amount of ocean
Sorry for the stupid names but illuminati will spawn you onto survival islands and boobies will spawn you onto a beach.

Try putting in random seeds with balanced biomes off and large biome size
To mine or not to mine, that is the question!
