"list of commercially used fonts"
That would be ... all of them! Including those from established
commercial foundries such as Adobe, Bitstream, and Agfa/Monotype,
individual designers, and both high and low quality fonts that are
free and shareware; not to mention proprietary fonts created for the
exclusive use of a single company.
Such a list would number in the tens of thousands, and would include
the different variations of typefaces produced by more than one
source, and totally different fonts that happen to have the same name.
Not a feasible undertaking.
