From a quick search of what's avialable rn if I had to get one I'd go with this one it's got good reviews, it's full metal and has all the contacts to work at full speed so I'd say odds are it'd be just as good as the ones I use. Though I've never used it personaly so take that with a grain of salt.
Hope this helps. Cf express cards are expensive and the speed is really nice for wildlife photography with thousands of photos. I use one of these adapters and got a high quality 2230 size nvme drive.
