Some of the nicer Perl software that I use currently is BackupPPC, which has been pretty solid despite the slightly subpar UI: https://github.com/backuppc/backuppc
And another interesting piece that I can think of was RemoteBox, which was pretty niche but still worked nicely: https://remotebox.knobgoblin.org.uk/?page=about
From the more popular packages, one should also mention exiftool, which was written in Perl: https://github.com/exiftool/exiftool
Probably also a lot of other pieces of software, though it doesn't seem like there's much of a large/active community around Perl, for example, have a look at: https://github.com/trending/perl?since=monthly and then compare it to something like: https://github.com/trending/go?since=monthly
In regards to other contenders, I think FreePascal/Lazarus should also be mentioned, since they're pretty stable, capable and perhaps some of the better ways to write desktop software!
Actually, that repo has lists like this for most languages: https://github.com/EvanLi/Github-Ranking
Isn't that Perl?
