My wife and I have twenty wooded are in Michigan, which we are not yet living on, but have been planning for months
Before we bought our land we had been reading and studying and searching for a suitable parcel for a couple of years.
Something I haven't seen anyone mention yet is "Observe". Watch your land through the seasons before doing permanent things on it. Watch what is growing where, watch where the sun passes across the land and by the seasons, watch the rain and where it flows, watch the winds - that's for starters
as you watch and observe these things, you will surely notice other things to observe.
In terms of priority for planning your homestead, water is top of the list. Where is it, how do you get it, how much do you get, how does it move across your land? On our Michigan property there is not much difference in elevation across the entire parcel, on the order of twenty feet over all. We have no running water (streams, etc.), but we also have evidence of seasonal runnels/streams and our lower lying ground is generally pretty damp. We haven't had the chance to observe over any period of time yet (we are still living in NJ, 14 hours away), so we don't know how wet it gets, and we have yet to see the water moving. We need to watch and learn and gain understanding of these movements in order to plan out how we will manage water on our property.
Holding it as high as possible and using it as much as possible as it passes through your land are fundamental principles of water management. Most of whatever we want to do on our homesteads is dependent upon what we can do with water. Water livestock, irrigate plants, even generate electricity - all can be done with water. And managing water is one of the most permanent, long-lasting systems you can establish on your property.
Setting up a small garden is a fine thing to do, not permanent at all, really, so you can shift it around to other (better) locations as you learn your land. Take your time about choosing where to place buildings and roads, they're relatively permanent and hard to relocate, plus poor positioning can have far-reaching results. Trees are another thing to take your time placing, as they can be generational
Choices about livestock are pretty transitory; you can bring in chickens today, replace them with ducks next week, try goats - etc. Infrastructure for animals doesn't have to be permanent, or even fixed in location.
Our plans include establishing animal systems as a very first stage in our homesteading, precisely because they are easily moved about, adjusted to fit what we learn through observation. And they can be used to prepare areas for gardening or other sorts of cropping.
And for a parting thought, spend more time thinking about the design of your systems than you spend implementing them
