I assume you're referring to this? It doesn't say anything about
.zshrc.

Indeed. The command you quoted is of the form
FOO=bar cmd arg1 arg2 arg3
which runs cmd with FOO in its environment. FOO is (generally) not
put into the environment of the executing shell. (In your example,
"cmd" is fzf and "FOO" is FZF_DEFAULT_COMMAND.)
I'm not familiar with fzf or how it's intended to be used, but the
fact that that command runs fzf immediately makes me think it's not
supposed to go into a shell startup file.

You took
FOO=bar cmd arg1 arg2 arg3
and turned it into
export FOO=bar cmd arg1 arg2 arg3
which exports FOO. In your example it also exports a variable named
"fzf". The other arguments become arguments to the export command
itself, which causes some trouble.

Perhaps you want this section? You will have to adapt their example
to use ripgrep instead of fd.
