(Except for 4) I'm no longer seeing cookies in CCleaner even though sites are telling me that they use them - including my bank.
Is CCleaner stopping them, or is that CCleaner is not finding them?

Edge, currently does not list cookies in the cookies to keep section. The developers are currently trying to fix Edge cleaning, uncluding this issue.
In the mean time you can clear them yourself from within Edge before closing it.
