I used Soot many times, for different things. I am 100% sure that Soot extracts control-flow graphs, and performs intraprocedural and dataflow analysis. They really do have a good community and good people who are willing to help you out. However, I am not quite sure if you can extract PDG or SDG with Soot. I read papers that claim they did it with Soot, but there are no source codes or examples that I was able to find (maybe you have to do some modification, I don't know). But I also do know that you can perform an interprocedural analysis with Soot as well.
Here are some tutorials for Soot. If you have any questions I recommend you to join their mail group and ask questions if you have any.
For WALA, I was also in a need of a PDG since that in its wiki it says you can extract a PDGs. Even though when you import the WALA project there are some example codes in it that you might want to look at. However, I was never able to get it running, because there wasn't enough documentation. Most of its documentation is pretty old.
Here are some tutorials for WALA.
Here is also a dataflow analysis test case code that they have. Maybe it can give you some insight. I strongly recommend you to look into their test cases, it might help.
Briefly, I believe you can all of the things you asked with Soot and WALA. However, personally, I was mostly able to do them with Soot. I guess it is more of a matter of how familiar get with them and how much you like one of them.
