I don't really care if anything else gets blocked as a side effect, except for Find My. As far as I know, `fmfd` and `findmydeviced` are the binaries responsible for that feature, so if I whitelist those binaries I should be fine.
Through my own usage of Little Snitch, it appears that all the iCloud-related features use individual binaries and that iCloud connections go to specific hosts for specific use cases (e.g. pxxx-contacts.icloud.com, pxxx-quota.icloud.com, pxxx-caldav.icloud.com). I'd assume the AI features are the same - specific hosts and binaries that I can block.
