      When trapdoors are placed at the top of a block, mobs can spawn on the following types:

      • Warped trapdoor
      • Crimson trapdoor
      • Iron trapdoor

      Mobs do not spawn on top the following top-placed trapdoors:

      • Oak trapdoors
      • Spruce trapdoors
      • Jungle trapdoors
      • Birch trapdoors
      • Acacia trapdoors
      • Dark oak trapdoors

      Mobs did spawn on top of top-placed trapdoors in 1.14, 1.14.1 and 1.14.2, but it was changed in 1.14.3 I believe it was. Not sure if iron trap doors have been spawnable ever since, or if that was re-introduced in 1.16.

      Personally, I think mobs should be able to spawn on top of them, when they are placed in the top of a block and are closed.
      It's kind of the same as other non-full blocks placed in the top position, like upside-down stairs or a half slabs in the top position.

      Either way, it should be consistent with all trapdoors.
