Some physical books:
“Parking Lot Pickers Songbook” is a good resource for bluegrass and gospel standards. It generally has the lyrics, the notes for the melody, and the chords for each song.
I also really like “The Daily Ukulele Songbook: 365 Songs For Better Living“, which I bought to learn the uke but I use for guitar all the time, too. It doesn’t have the guitar chord shapes, but if needed I look them up in my other resources.
And I totally agree with others about looking for YouTube lessons on songs you like.
Ultimateguitar.com is a site with crowdsourced tabs and chord charts. Accuracy may vary, but I use it quite a bit when I’m trying to learn something new.
Have fun branching out!
