I’m aware of code that detects bit flips via unreasonable value detection (“this counter cannot be this high so quickly”). What else is there?

If they're hundreds of bytes or more, then two copies plus two hashes will do a better job.
If you're doing something that's more centralized then one hash might be simpler, but if you're centralized then you should probably use your own error correction codes instead of having multiple copies.
