Thanks for the explanation. So it’s always assumed you are talking about the
REQUEST_COOKIE_NAME, and the REQUEST_COOKIES part just tells you what to
ignore. Cool.
However, it’s still not working. Now I have
SecRuleUpdateTargetById 981318
"!REQUEST_COOKIES:CFAUTHORIZATION_cfadmin"
The logs show everything starting up fine, and only one block – the first time
it runs into that cookie.

Understand that.
My version of the exception means "exclude rule 981318 from checking the value
of the cookie which has the name CFAUTH..."
You're version of the rule means "exclude rule 981318 from checking the name
of the cookie which has the name CFAUTH..."
Both versions of the exclude config are specific to that cookie name.
The log you've shown suggests it's the cookie value (for cookie CFAUTH..) which
is triggering the rule not the cookie NAME itself. This makes sense if the
cookie value contains double quotes as that is basically what rule 981318
checks for.
There's rarely a need to check the cookie name, so mostly you want to check the
value. However if your cookie name included an SQL word (e.g. if your cookie
was called abcTRUNCATE123 for example) then you might want to exclude the
cookie name from SQL injection rules.
Thanks,
Barry

I'm trying to remove the rule when the cookie *name* is that CFAUTH... The
cookie value changes with each session. What the have in common are enclosing
double quotes, but I only wish to whitelist them when the cookie name is as
above.

You are whitelisting the cookie name and not its value.
Try this:
SecRuleUpdateTargetById 981318 "!REQUEST_COOKIES:CFAUTHORIZATION_cfadmin"
