This question makes no sense. If you want to reject mail to (all or
most) addresses that don't correspond to a particular user's mailbox,
then you should not have a catchall.
So which is it, do you want to deliver mail for typo or otherwise
incorrect addresses to a catchall mailbox or do you want to reject
them. You can't have both...

That's not how catchall's work, for that you'd want "always_bcc"
"recipient_bcc_maps", not a "catchall". A catchall address receives
mail that no other mailbox would receive.
It seems when you say catchall, you mean something else entirely.
To make that concrete, send configuration details and sample logs.
https://www.postfix.org/DEBUG_README.html#mail
$ postconf -nf (with unmodified whitespace and linebreaks)
$ postconf -Mf (with unmodified whitespace and linebreaks)
logging of some messages to illustrate what your "catchall" is
doing.
