@frgo I never use supplier supplied libraries.
I have my own 'style' and fixed set of parameters that I add to the symbols and external libraries are generally very limited in data.
In my 20 years being a designer, the libraries may have contained about 1000 parts. Of those parts in our library, there is a 80% that the component has been used on one of the designs.
Using external libraries, that is not the case. First you can have many different libraries, duplicate symbols, huge amount of parts, lack of detail, naming variance, etc.
Using the graphic symbol for a few components like FETs and transistors is ok, but for the rest, I do all myself.
Now one big difference between my designs and designs done by @robertferanec is that I also do not use reference designs. In part the designs are more simple (no high speed, high pin count nor memory).
Once a first component has been made, like a resistor, it is merely a question of coping it and adjusting the parameter values.
I only use schematic and footprint libraries, no database.
Multiple libraries, each for a specific purpose - resistors, capacitors, discretes, power, etc.
