I also like pockets in a bike bag, but I've found the selection limited. I eventually chose this extra large "Big Poppa" MIK rack bag.

It lacks interior pockets, but has a couple on the outside. The fold out pannier covers can also be used as storage pouches without deploying the panniers.
To compensate for the lack of interior pockets, I use these small canvas zipper bags to organize the items I carry. They're color coded, so I can easily find what I'm looking for. I also find it easier to access the contents instead of reaching into interior bag pockets.
