While filing a radar (feedback assistant post nowadays) I've came across the following console log from the system at the time of request to start monitoring.
rejecting read of { com.apple.CloudKit, mobile, kCFPreferencesAnyHost, /var/mobile/Library/Preferences/com.apple.CloudKit.plist, managed: 0 } from process 1083 (FamilyControlsAgent) because accessing these preferences requires user-preference-read or file-read-data sandbox access
Couldn't read values in CFPrefsPlistSource<0x143018430> (Domain: com.apple.CloudKit, User: kCFPreferencesCurrentUser, ByHost: No, Container: (null), Contents Need Refresh: Yes): accessing these preferences requires user-preference-read or file-read-data sandbox access
Maybe some capability they didn't document is missing here, hope the next beta version lands soon and fixes it.
