I would tend to generally agree here.
Pilons and calcs - esp if there's no good keystone fragment - are long, greuling surgeries sometimes. The worst part is that, even if you get a good joint reduction/alignment, there's still a very high chance of arthritis 😛. The nice thing about trauma is that expectaitons are generally low, and you can always blame the injury. Before surgery, they couldn't walk. After surgery, if they can even walk at all, it's an improvement. Any residual arthritis, deformity, etc is from "the very bad fracture"... and not a crummy ORIF (unless a lawyer - or another gutless competing surgeon - throws the orig treating doc under a bus).
For elective, I'd agree with anything neuromuscular being the most complicated of elective recon... cavus foot definitely, and I'd include flatfoot as a neuromuscular imbalance on a very basic level also. Charcot recon can also be hard, but like trauma, expectations are rock bottom if you prep the patients well pre-op. They can't walk without a CROW, so any smaller brace/shoe is a big success. The Charcot recons are tough due to bad bone and bloodflow... but the neuropathy and "well, the severe diabeties caused the amp" are always your easy (and often true) bailout for failure.
I would really be careful to underestimate any elective procedure, especially in (surgical) virgin feet. There is just nowhere to hide from complications. A Lapidus/Akin or even a hammertoe with plantar plate tear isn't viewed as very hard, but if it's a Chanel purse toting doctor or lawyer's wife from the suburbs, you had better bring your "A" game. Unlike trauma surgery, Charcot, etc, the elective is a game where the stakes are raised: everything from the scar to the neuritis to bleeding through the bandage to a minor cast complication to the slight malrotation of the toe post-op is a potential land mine.
...in terms of "wow" value, I guess Ilizarov, ankle implants, and IM nails have the most "oomph" of any F&A surgery. I don't really think either IM nails or static frames are all that hard (dynamic ring frames are, though), and I just don't agree with ankle implants based on principle. Nonetheless, those 3 - and probably heavy trauma like pilons or bi and trimall ankles have the most "cool case" value for pod students, 3rd party XR lookers from other med or non-med specialties, etc.
