Hi,

Failed engine mounts (or engine pads in Volvo speak) could be one of the culprits. Some vibrations which still persists despite replacing parts could be due to engine mounts. I've watched your video - the RPM needle still looks smooth to me.

Regarding the rough idle when wet/cold weather try spraying WD40 inside the dizzy cap to repel moisture.
