I'll add more to this as I go along, but here are a few good seeds to start with-
-1598947962 - This has five villages close together near the spawn. Two you can see at spawn, the one to the east has a stronghold under it. There is another east of that, and two more villages just south of the two you see at spawn.
-1600064606 - Two villages bordering a nice mesa biome at spawn. One village you can see at spawn, the other is just east of there. Continue east through the mesa biome and at the end you'll hit a unique desert village that has part of it in swamp and part in mesa.
-475823380 - Spawns you by a town with a mineshaft right under it. Borders snow biome.
-1068971341 - The spawn isn't that interesting other than the temple, but this one has something I've never seen not a huge distance from start - a stronghold intersecting a mineshaft. Go to 1042, 12, -1160 to 1092, 15, -1132 or so on this to see what I mean.
