The idea behind the topic - getting sufficient certainty on the subject for myself and other new users alike - could not be gained.
For this reason it is discarded.
Remark:
This subject is rather complex.
For someone liking to enter more deeply into the matter, please see Fillet on cylinder edge bumpy for instance.
For the quick passer by, stripped down to the titles meaning, the accuracy may be set by the user in the following locations:
1) Preferences -> General -> Units -> Number of decimals
2) Preferences -> Part Design -> Shape View -> Tesselation
- Maximum deviation ..
- Maximum angular ..
3) WB Sketcher: (Combo view) -> Tasks -> Advanced solver control

As a user of FC, I definitely like to be in control of the precision, by which my CAD-model is calculated by FC (irrespective of the view presented by whichever SW). There are cases, I even need to control them due to various reasons and requirements (not to be listed here actually). 'Fine' modelling needs processing time, understood.
What I could find until now was:
Preferences -> General -> Units -> Number of decimals:
It appears as if the no. of decimal places used for computation here would not be influenced by the user. If this is true, it would not matter for the modelling precision. Otherwise, is would be neccessary for the control of the processing precision.
Preferences -> Part Design -> Shape View -> Tesselation:
Maximum deviation depending... (rest not fully understood) allows a degree setting. To what I understood by now, this IS influencing the coarseness of curved surfaces of a models shape.
