I recently rebuilt my whole station. Among other things, I neatened up all the wires and cables. Naturally, this resulted in a bunch of new RFI problems.

That is a symptom of failure to implement proper bonding and grounding. See N0AX's ARRL Book on the topic, and/or the slides for my tutorial talk. Don't let "audio" in the link fool you -- 99% of it is about grounding and bonding for lightning protection, and for the prevention of RF in the shack.
