So about a month back I started putting together a macOS app to do a better job of revealing those kinds of details - and it turns out it's useful for a lot more besides. I've even heard from folks who found old plug-ins they've migrated from system to system that only contain PowerPC or 32-bit x86 code! Based on community feedback the app has grown and evolved while retain a focus on speed and simplicity. Today, it's capable of scanning thousands of plug-ins in a second or two, refreshing its list automatically as plug-ins are added or removed:

The simple interface disguises a variety of helpful features. Sort by any column. Turn on filtering and type a few characters to narrow the list to matching plug-ins. Double-click on a publisher name to visit their web site. Select any number of plug-ins and you can open Finder windows selecting them wherever they're installed, or copy either the installation paths or full details to the clipboard for use in other apps.
It's available for free on ThinkerSnacks.com with a Mac App Store option for those who would like to express their thanks, or get the convenience of automatic updates and added security of Apple's review process.
The publisher identification feature is of potential interest here, as there's no way I can track down every publisher out there and make sure I know what identifier scheme they use and what their web site is (though it does currently know about more than 400 publishers!) If you work for or run across a publisher it doesn't know about, capitalizes or spells incorrectly, or links to the wrong URL? Please feel free to let me know. The PlugInfo page linked above includes a "support" section with brief instructions regarding what would help most.
