Best apocolyptic mapssentiment_satisfied

does any good maps for minecraft java edition that are like the real world but apocalyptic for a zombie apocalypse themed survival thing or at least a world that has been completely explored with the lost cities mod(it doesn't work for me its really laggy) cuz i'm making a zombie mod and it has guns, new zombies, cool weapons, useful items and new effects(i will answer any questions about the mod in the comments)i'm bad at animating and coding so the mod is still in progress while i'm getting help from someone i know that knows coding but back to the map i need a map with these requirements: 1. cities thats obvious 2. nothing can be made out of anything weird like for flooring it uses warped leave things and then it requires a textures pack 3. all the stuff in the map should function with 1.19+ so no coper golem statues or pale moss or anything(i use 1.20.1) 4. this is optional but i would like it to have a data pack that makes zombies not burn and disable creepers skeletons and spiders and make zombies spawn more often like 2 spawn every 8 minutes or something so does anyone know any maps(also there is no limit for the size of the map not file size but world border size)
