First, thanks to you and everyone for helpful suggestions.

I'll focus on this suggestion now l because it sounds like it could save
me a lot of time.
focus on one card first then clone it!:)
But before I start, I have to ask if it is actually possible to clone a
bootable image (that's what I have, right?) from one SD-card to another,
if the SD-cards are a bit different?
I have one 64GB Extreme, one 64GB Extreme PLUS and one 32GB Extreme
PLUS, all SD-cards from SanDisk.
Let's say I start with the smallest, what's the command line sequence
for cloning it onto e.g. 64GB Extreme PLUS?
One of the reasons I ask is that I got the impression that the speed
optimisations that are made by the box-fill-disk command somehow has a
dialogue with the card when the card's read/write parameters are set:
"Optionally tune ext4 filesystems for specific MicroSD NAND chip pattern."
If each card type (and size) talks back in its own way, then I guess I
can only clone a card onto cards of identical type (and size)?
