If you have used CCC's or Tinkertool Systems Full Clone{/I] you will recognize the process (I believe Super Duper's developer rejected offering that option)
The target drive will always be completely erased. You must approve the erasure before CCC will proceed. (I haven't had time find out how that happens with automated clones.)
The drives entire volume structure is first copied and then everything else is transferred [i]en mass without regard to files and folders per se. The target becomes a true mirror of the source, warts, winkles, and all.
I have no explanation for my initial installation and startup difficulties but I have no reason to believe they represent any issue with CCC and hopefully not with macOS 11.0.1 running on Intel instead of Apple SoC. I will not hesitate to use or rely on CCC in the future and look forward to using it on Apple SoC next week.
Obviously I misjudged the priority Apple assigned to cloning.😢
FOLLOWUP
I just installed CCC 5.1.23-b3 (6104) and tested it out. In the process I made some discoveries.
If the Destination drive is BLANK CCC will give you three options that only appear when you actually initiate the cloning process: 1. Erase the destination drive and create a bootable clone (this is the Apple en mass clone I described previously) 2. clone the entire system into a volume on the destination drive 3: clone only the data volume
If there is a bootable system on the destination There are two options offered: 1. Copy All Files (this copies only changed files and results in a bootable system) 2. Copy Some files - bootability not considered
I haven't tested all the permutations yet, but I will get around to it eventually.

If we knew what it was we were doing, it wouldn't be called research, would it?
