This is awesome, and I feel that this is indeed Alfred's Clipboard Manager on steroids. You did mention trying out Alfred. Without installing ClipBook but reading up on the features, what is missing from Alfred?
Alfred's Clipboard Manager is pretty navigable with the Keyboard; the history is as much as there (I don't know about being infinite), and I can also see the preview, etc.
I used to have Clipboard managers, but with Alfred + Powerpack, I did away with another program running on the menubar/background.
Edit/Update: I just checked Alfred and I can keep plain text, images, files list, for 3 months.
I don't mind to pay for a software. Most of the software costs like two cups of coffee. The only feature I miss in Alfred/Raycast is that I cannot resize the clipboard history window to see more content in the preview panel. I copy large text and source code files. It's hard to quickly look at the source code in a small preview panel.
Maybe it's just me and I didn't find a way to resize the window. If someone knows how to do this, please share with us.
