CC should run fine. It doesn't care if the play store or google services aren't installed. A larger problem could be moon+. I don't know if it wants to check a license, but if it does then it won't run.
Another issue could be the desktop manager. I thought that the default manager on my Onyx and Boyue devices was terrible, trying to be both an app manager and a library manager. I ended up rooting the device and installing the Nova launcher. It might be that you could install the free version of Nova without root.
I think that several CC users have the
Onyx Boox C67ML, which is approximately the same price.
