While not based on what you have seen watched or are currently watching, here is my personal list of anime I have really enjoyed or am currently enjoying. Who knows, maybe you’ll like one or more of them.
Ghost in the Shell: Stand Alone Complex and Ghost in the Shell: S.A.C. 2nd GIG - Action? Check. Political intrigue? Check. Interesting philosophical questions? Check.
Moribito: Guardian of the Spirit (AKA Seirei no Moribito) - Quite a bit less action, but generally more of what I enjoyed from Ghost in the Shell, only in a fantasy instead of science fiction setting.
Mushishi - While this series has strong supernatural elements, the focus is more on the personal lives of those effected by the “Mushi”.
If you are willing to track down quite an old (early 80s) anime, then you might try Armored Trooper Votoms. I’m not sure what it is about it, but I found it quite good.
Lastly, since I saw that you have Code Geass in your list, you might try Tsubasa: Reservoir Chronicle and xxxHolic.
