I shoot about 3,000 photos per year with a Nikon D500 and edit them in Photoshop 26.9. Very occasionally, 1–3 images a year show severe corruption or banding like the example I uploaded. What usually causes this kind of rare, recurring file damage, and what should I check first?

That is a corrupted image file. There's a multitude of possible causes, but the most likely would be a bad cell on a card. You could try doing an in-camera format just in case the file directory has gotten a bit messy, but you should be doing that already.
If the card is SD or XQD you would need a third party program to do a full low level format/rewrite (secure format) which should force it to identify/mark bad cells. IMO, SD memory is so cheap, and somewhat fragile, that I would just replace it. If the card is CFE-b there is a card reader that has the ability to reset a card to factory new condition. It can clear/rewrite all tables, all memory cells, and remap the card (bad cells/error correction); among other things.
Other possible causes are a bad USB cable, bad USB port, weak connections, etc.

This looks like file corruption rather than a camera sensor or Photoshop problem. The most likely cause is an issue with the memory card, such as a bad cell or file-system problem. A good first step is to back up your images and format the card in-camera regularly. If the problem continues, replace the card—especially with SD cards, since intermittent faults can be hard to trust.
Other possible causes include problems during file transfer, such as a faulty USB cable, bad card reader/USB port, or an unstable connection. If the corruption appears only after copying to the computer, test a different reader, cable, or port.
If your card type supports it, a full low-level/secure format with the appropriate utility may help the card identify and remap bad cells, but if corruption happens more than once, replacing the card is usually the safest solution.
In short: suspect the card first, then the transfer path.
