What rhythms for rock?

I am a 63 year old drummer (retired) that bought a set of Meinl Headliner congas 4 days ago. I absolutely love them---I practriced 4 hours the first day, 6 hours the second, 5 the third... I am amazed at the variety of sounds that come out of one drum.
My current practice routine
For the past 4 days, I worked on my strokes, practiced a salsa rhythm, then jammed along with whatever random song came up on Pandora music (to throw some curves at me).
My question
I randomly picked salsa as my first beat to learn. Eventually I will be sitting in with rock or country rock bands, and not latin. After I get the salsa rhythm down, what rhythms would be best to learn that I may be able to apply to rock music? Any other suggestions for a drummer learning congas for rock applications?
