Have you tried some of L.E.Modesitt Jr. sci-fi? Action scenes can be a bit on off, but he does tend to spend more time posing ethical / morality / philosophical questions about the nature of society as it develops higher technology. What I find a touch interesting is how he'll write one story posing that x is correct, then a few years later he'll write another that takes the opposite viewpoint.
Although things that seem constant do tend to be thoughts on how the more advanced the technology becomes, the more personal self-responsibility and transparency is required.
Edit: And some can be a touch fun pulpy sci-fi wrapped around it.
