I'm graduating from Evans this year. I would say one of the biggest "perks" of Evans is how adept the school is at networking for graduates of their program. Evans graduates are everywhere--there are plenty in federal government. That type of network may be less important to you if you're planning on returning to your old job, but it never hurts to have plenty of folks you are connected to. Did you look into the executive program at all? If you already have quite a bit of experience that may be a better fit for you--and it's faster. There are quite a few folks who came into this program with some experience and many who are currently working, but that group is smaller than is the less-experienced and younger part of the cohort.
There are some courses around cybersecurity at Evans and you can also take electives in other colleges for that. Big data is a hot topic on campus at the moment and more and more courses are popping up.
I did the MPA program concurrently with the MSW and I also work in social policy research at UW. I added on the MPA because I wanted more quantitative coursework and it has been good for that. My main critique of Evans is that it lacks contextual coursework--it really is a tool based, quantitative, professional program. For me that wasn't ideal on its own, which is why I did the dual degree, but if you are focused on quantitative work, this is a great program. I've made it through while working and raising my daughter here on my own, but my oh my would I have appreciated some family support. If I was in your position, that might be a defining factor for me.
I'm not sure if that helps at all, but feel free to hit me up with any questions!
