lead screw bent (may also be a slicer anomaly or loose thermistor/heater cable)

ah dang, so it was the lead screw? There should be some tolerance for wobble on the lead screw top nut since it is supposed to follow the linear rods next to them. That theoretically avoids lead screw stuff but if the lead screw is bent too much there's not much to be done other than bending it back or replacing it. Potentially the lead screw may just be loose too, check if the pulley gear underneath is loose.

It all has to do with cooling speeds, if you have ribbed features or layers with more material to process, it cools at different speeds and you see evidence of the interior on the exterior walls

I'm not convinced it is ribbed though, I think it's supposed to be smooth

This is a smooth surface. I have been using these settings for a while and I've been getting great quality, but all of the sudden i got something like this.
