Yes, Lewmar covers that in their Technical Guide.
On their table they mention that if you have fractional rig you should go with
the square area of the sail. For masthead rig they recommend to match with the
length of the boat.
For a EVO ST40 used for genoa sheets here is what they recommend:
Max of 300sq/ft ( fractional rig ) or 33 foot length boat ( mast head rig ).
I assume this for a #1 genoa.
Best size for a ST40 on a masthead rig is 31-34 feet , good between 34-36.
SWL is 1700lb and sheets up to 1/2 in.
At least they provide all the info to make a good choice and how to properly
set the orientation and angle.
Good things to know since we do it only once every 25 years :-)

hole filling, etc.
I replaced the original Barient 28's on my LF38 with a pair of last generation
Lewmar 65's that I bought from a guy who replaced them with electric winches.
Yes they are a bit big, but they fit, are easy on the crew, and I don't have to
look at non-factory patch jobs made necessary by undersized winches. My 28's
went to a J29. As Jim notes, no one on either boat has ever complained about
the oversize winches.
I suggest the 30's on the Beneteau 39, although they may well be the best thing
on the boat, may be on the small end of the acceptable scale. Many of the
Beneteau's have smaller rigs and headsails than similar length C&C's, so they
may be fine.
Choices, choices.

With all due respect to Rich, I don't think you need the 50s. I sail on a
Benne 39 with Lewmar 30s! They are the best thing on the boat. Epoxy the holes,
and if necessary, get a piece of teak or starboard and cut it in a circle to go
under the winch to cover the space occupied by the prior winch.
