Are you planning on living there? not anytime soon, temporarily
Are you looking at starting a farm, or just having a homestead? start a food forest
Do you want to have animals? I am open to it
Sorry for replying with questions, but before I suggest anything, I need to figure out what your specifics are.
Depending on how much time you can invest on the property, you might want to start small. One of the biggest problem I have seen with a larger scale food forest is grass control. Those small trees will be slowed down if they have to compete with grass. Planting 50ish acres is a big undertaking. You could start with a general plan and establish it in phases, based on how much time you have. I think the most important is to get the earthworks done (if necessary) and then planting can happen over multiple years as time and money permits.
Once the trees are established, the grass competition will not bother them as much. Off course, you could just let the trees sort themselves out and not provide them any assistance, but you have to be prepared to loose more of them.
If oaks grow there already, I would say it is a good one to plant. Acorns are edible and quite tasty. Chestnuts might do well too. Look into Badgersett, they have Neo-hybrid Chestnut that would be well suited for your climate.
