Aye. I went looking for that in the Python re module docs and could not
find them. So the comprimise is match any word, then test the word with
isupper() (or whatever is appropriate).

The tricky bit with f-strings and regexps is that \w{3,5} means from 3
through 5 "word characters". So if you've got those in an f-string
you're off to double-the-brackets land, a bit like double backslash land
and non-raw-strings.
Otherwise, yes f-strings are a nice way to compose things.
