Probably Paul Friday's varieties would perform relatively well there, but
growing peaches organically is pretty his and miss and often the older
varieties are more resistant to brown rot, which can make organic growing
close to impossible for peaches.

The Harrow Station varieties are often evaluated for BR resistance and a
good one that is highly flavored and produces large fruit is Harcrest.

Madison is another variety that is relatively winter hardy and resistant.

Of course, if you have a lot of cloudy weather leading up to ripening
peaches can be bland.  Then the higher brix varieties can show their
advantage.  For me that includes several nectarine varieties, but organic
growers probably shouldn't bother with nects.

Some good ones, in sequence of ripening are Rich May (gives me flavorful
but very small peaches in late June often before BR is a problem), Early
Star, Red Haven (which you know), Ernie's Choice, Veteran, PF 27 and 28,
Encore.   If your season is long enough, Victoria provides me peaches in S.
NY into Oct, ant they are pretty good.  Another late and very unique white
peach is Indian Free.  Very late peaches are also less susceptible to BR, I
think.
