So I found this seed literally by just creating a random world, and it's very good. First off you spawn in a village that is situated in the middle of an Acacia, Oak, Warm Ocean and a Jungle biome. There is a ruined nether portal right beside the village and multiple ocean ruins nearby, in the caves beneath I counted at least two mineshafts almost directly under spawn and 6+ dungeons. I also found a weird crater that leads straight down into a massive cave.
