Installing the kde-standard package is not what you would like to install in the first place as a user who wants to have fine grained control over the packages on your system. Given the large list of things that you do not want, I would recommend removing kde-standard and install plasma-kde-desktop. The latter is like a minimal kde.
However, we can also impose to the package manager that we installed actually all of the kde-standard dependencies and recommends manually and not as a dependcy :
aptitude unmarkauto "?reverse-depends(kde-standard) | ?reverse-recommends(kde-standard)
Note: Before running such commands I always recommend to run aptitutde a first pass with the -s flag, that simulates the to be performed actions.
After this, you can remove the kde-standard package (aptitude remove kde-standard), and then proceed to removing the undesired packages. Depending on the way you installed kde, aptitude may recommend to remove also the task-kde-desktop, which can be safely acknowledged.
