For the first time in several years with many cards, my Mac ImageCapture is getting errors downloading a few specific images off the camera. I tried multiple times. Perhaps the card has some corruption on it (it's not an old card). Does the camera have any way of fixing the issues during Formatting or I should do it out of the camera (on a computer with an app for data recovery and file system check)?  It's an expensive high-end SD card so I don't want to just throw it away. What's the best way of handling those kinds of errors?

Funny story, I had an SD card that always corrupted one specific photo. What I think it happened was thet some bits were flipped when writing to that specific region. I could still download the photos but opening them they were half pink and half distorted. I kept using that card eventually since I only did photos for my self but after a few years I upgraded to something else because of the size of the card.
 

Now to answer your question: I would low level format it in camera or in Mac a few times and I'd use it in order to test it if it fails. Benchmark it, write some files on it, fill it up, copy the files back, etc. Stress test it. It it fails under the stress test, then you need to buy another card, if not and only some files are corrupted, then expect that it will go bad (or it might not, but assume it will) and then ask yourself if it's woth buying a new card now or losing some photos and buying it later.

Now it depends on how much do you care about that photos. Working for a client? Buy a new card. Hobby? If it's bothering you buy another card or use the second slot to save JPEG/HEIF and download the corrupted files from there.

BTW, I never got rid of the corruption of only one photo on that card.

If it's an expensive card, it should have a warranty - I'd recommend asking for a replacement. The maker of the card probably doesn't get a lot of warranty claims, so they'll probably simply replace it.
