Some of the Friday trees are excellent but not all. I have PF Lucky 13. The peach is super mild, my wife likes it, but I find it rather bland for my tastes, I plan to top work most of it over with other peaches. I will leave one scaffold. It’s not like it is bad, It is just not my cup of tea.
@Olpea is familiar with many of them, he may have suggestions for ones to try. Or at least mention what works for him.
On rootstock i like Lovell. I keep them at about 7 feet tall. Do not get citation, in your area it will do poorly. Most others will work, avoid Guardian too. Great for the southeast, but not us. It seems Adams as typical is out of about everything decent. Many other tree nurseries are around too.
I would take my time and google all choices before you buy, and search here too!
Scott has rated peaches for over a decade and puts out a list of what has been working for him on this board.
Here is one from 2015
