+\(bu Do I ever need to use an empty macro argument ("")?
+Probably not.
FWIW, man-pages(7) says it's OK to use empty string for the 4th
argument of .TH:
"For library calls that are part of glibc or one of the other common GNU
libraries, just use GNU C Library, GNU, or an empty string."
There used to be a lot of such .TH calls; now there's only a few left:
$ grep -r '[.]TH .*""' man*/
man7/posixoptions.7:.TH POSIXOPTIONS 7 2021-08-27 "" "Linux Programmer's Manual"
man7/bpf-helpers.7:.TH BPF-HELPERS 7 "" "" ""
man8/zdump.8:.TH ZDUMP 8 2020-04-27 "" "Linux System Administration"
man8/zic.8:.TH ZIC 8 2020-08-13 "" "Linux System Administration"
