"After initially having similar thoughts about it being "obsolete" and a "dinosaur", I quickly realized how resilient and flexible the language is (I know the flexibility can come with some criticism)."

Not obsolete - can affirm. All of the Oh By[1] back end is written in perl, circa 2016. We use apache + mod_perl and are very happy with this environment ... just like we were in 1998.

Any thoughts about switching to plack? It seems like maybe you could get some low effort performance/developer experience improvements.

Obsolete was the wrong word - Perl definitely still works (very well for certain things). Cool to see new applications being developed in it still!
