I’m one of those people who loves to sing ALL the verses. It would be fun to find such a resource and compare all the hymnals and question the editors and find out why they picked the verses they picked.
It is fun and worthwhile to study. You’ll often find verses added by multiple authors over the years and choices of verses to fit the particular doctrinal bent of various groups as they created hymnbooks, etc. Sometimes you run into forgotten gems with rich, deep, Biblical contnet that haven’t been used for a long time due to hymnbooks desiged to appeal to the broadest audience possible.
If you like that kind of study, you should take a look at Hymnary. They have an index of hymns with historical and biographical information, and even charts showing how popular each was in hymnbooks going back to the 1700s.
There is also a feature where you can enter a bit of a tune on an onscreen piano keyboard and search based on that!
