Yes, I misspoke. In this order:

If the client demands CSD (e.g. has a headerbar), CSD will be used regardless
of server preference.
If the server prefers SSD and the client has not demanded CSD, SSD will be
used.
Else, CSD will be used.

I don't know KWin or GTK+ well enough to answer your other questions, I'm
afraid.
