There should be a good enough job market for developers and IT peeps. One of the biggest advantage probably is flexibiliy, you can in finance, medical or even your own start ups and of course wfh :)

Im not quite sure about manvi or other army careers, but I have heard you get good facilities in long run esp for your family. I think u might need GC to enroll. With army, you can sent to different sites so you might wanna think if you are settled or planning to do soon. It might be more exciting and physical than IT jobs though.
