You really have unlimited options, yet it matters what "feel" you are going for.
For example, C blues scale would be "bluesy, duh. C Minor Pentatonic would be more "rock." C Major Pentatonic would get a "happier" feel. Mix the major and minor for added flavor.
And we continue...Mixolydian is rock with a twist (many players use this, yet mix it with other scalar lines).
Then, if you want more...you can use C Dorian to add some interest. Really any scale "can" work, depending on how you use it.
So, the question is what are YOU looking to create as a feeling? It's a I, IV, V progression so you can do LOT'S with it.
The rhythm will also give a "feel" to the music, try to complement the feel while also having fun and creating interesting lines.
In my experience, the best thing to try is experimenting with the modes and scales to learn how each sounds in the context of the music.
Creating tension and/or resolve. Have fun, it's wild when you can mix things up and take the listener different places.
Hope this helps.
