Your previous descriptions were good; clarification cannot do any harm.

Very wise. If you are familiar with each stage of the installation you
can more more easily spot anomalies. "Expert"=="more control".

That's ok. I tend to be more promiscuous; usually on a whim, like
wanting to put a particular entry at the top of GRUB's menu list.

When you do 'update-grub' do you still get no "set root=" line for the
SD card in the grub.cfg?

That's ok too. I often don't bother with a swap partition. Some of my
machines have less than 4 GB of disk space. I see space for packages as
more important than swap space.

Yes.

I'm at a disadvantage here. I do not have an SD card. I do not have a
USB hub. However, I thought USB sticks and SD cards were the same (or
at least similar) when it came to booting.

Does that not substantiate what I said just now?

I cannot believe your install to the card would be capable of criticism.

I mentioned "bug" in another mail. I wish I hadn't. It is not that bugs
in GRUB or the Debian grub package do not arise, but I'd want to know
more about SD cards before committing myself.
