Here are a couple of my favorite links for peach information:
https://growingfruit.org/t/2018-peach-report/17902
https://growingfruit.org/t/further-evaluation-of-winter-damage-of-peach-buds/9818
Both of these posts are from @Olpea, they have been very helpful to me.
Personally, I would go with a standard rootstock like lovell. Peaches are not too difficult to keep small via pruning.
From a fruiting standpoint, they get going relatively early. I have been able to fruit a few peaches the second year on many that I have planted, you just have to thin them down for good quality. By year 3 you should be getting fruit pretty reliably, assuming no cold damage.
