Had problems earlier with loud knocking and vibration. I replaced worn guibo and exploded center bearing but there still some small vibrations upon acceleration, especially with 1st and 2nd gear. As it's winter here I also occasionally (maybe 1/10th time) hear silent tapping noise when
taking off with rear tires sliding. Tapping goes silent quite quickly though

Could worn driveshaft CV Joint cause this vibration or are the outer CV joints gone?

Rare that A raar half shaft CV joint unless severely spent would cause your isse. If you haven't replaced all joints on your driveshaft, then that is likely your culprit.

Thanks for reply! U-joint was also checked and was OK when I replaced flex disc and center bearing so I'll probably have to change the driveshaft CV joint.

Just to know in the future what are the usual symptoms with those worn rear output shafts ?
