These are not compression gloves, but my hands are closer to a medium, I bought them in small, they are relatively stiff, and they provide a lot of support. They also have lasted longer than any other fingerless gloves I've owned, and their padding rivals any bike gloves I have tried. I've worn the hell out of them for 18 months, not just on the bike, but also for driving and just to keep my hands warm (I have mild Raynauds.) The velcro is finally getting a little less sticky, but still works! They look a lot like typical Amazon gloves that start fraying in 6 months of use, but for whatever reason, they don't.
I have grade III osteoarthritis in my hands, where the thumb meets the wrist-- metastarsals or whatever-TF. The best solution actually was new grips. With hand problems, yes, you want impact protection, and you want support, so I understand why stiffness is important, and the right gloves do help-- try a few. But getting a handlebar riser for my second bike and modified grips made a huge difference, LMK if you want a link to the parts. Here are the gloves, which-- weirdly-- are not even bike gloves, they are mechanic's gloves:
