I’ve tried Yoink as well as Gladys and Copied and others. As is often the case what I’m finding in actual use is that Apple’s native apps are likely the best option for me. I can drag and drop into Files app for storing temporary images or other documents or, just as easily for text, images, pdfs, I can drag into and out of Notes. And of course both of those apps have action extensions. They both sync up very quickly to iCloud should I need to hop to another device.
