I don't know if this helps answer #3 or not. I have ran Debian from a
microSD flash card before but the card reader was attached via USB.

It didn't last very long before the flash card degraded. I think running
an operating system on flash used up the read/write cycles too quickly.
I eventually decided to find another solution. But it may not be an
issue for your use case.

I don't think so. I have a low power industrial pc used as firewall. It runs
on Compact Flash card for >6y now. I recall there were at least 100000
write cycles per sector and self diagnostic, so I would suspect something
else would be the problem.

CF cards were much more clever from the beginning compared to cheaper
alternatives (like SSD or MMC cards). I would expect them to have better
wear levelling than a common SD card.

I would be surprised that a CF card be more clever than a SSD.
However 100000 erase/write cycles/block implies the use of NOR or SLC NAND flash memory chips, the types with highest endurance but lowest density. I doubt you can find this in SD cards. MLC NAND endurance can be 100 times lower.
