But wouldn't "surrogate clones" as the category be closer to twins than siblings? They would be closer to twins than fraternal twins.

  Honestly I don't think it's very clear. The practicalities of cloning processes make it so that we are very far from exploring what's in principle possible. All of the cloned mammals so far have died pretty young even when the original organism lived a long and healthy life, so in that sense they are technically way more different than even siblings. Of course, this is almost certainly just a limitation of our currently imperfect cloning technology, so it's hard to judge what a perfected cloning tech would do. Of course, certain aspects of appearance are known to be almost exclusively genetically determined, such as eye, hair, and skin color. Some fine details are known from identical twin studies to not be fully determined, such as fingerprints (twins have slightly different fingerprints). For the majority of other fine details, it's actually pretty unclear.
