In Java Edition 11 mob types can spawn in Sulfur Caves — hostile mobs: Sulfur Cube, Creeper, Skeleton, Zombie, Slime and Cave Spider and 3 more; ambient mobs: Bat.
Sulfur Cube has the highest spawn weight among the hostile mobs: 100 of 315 (31.7%) in Java Edition.
Yes. Java Edition lists 10 spawn entries for Sulfur Caves, Bedrock Edition 11. For example, Sulfur Cube has a weight of 100/315 (31.7%) in Java and 150/436 (34.4%) in Bedrock. Use the edition switch above the tables to compare.
Each spawn attempt first picks a category (for example hostile or passive mobs), then one mob of that category at random, weighted by its spawn weight. A mob's chance is its weight divided by the total weight of its category in the biome — so the shares in each table add up to 100%.
