Congrats on your property!
I don't really have any feedback on your plans, but maybe some experience to share, because I have lived at my current property for about 11 years in maybe a similar climate on a north facing slope.
The thing about a north- facing slope is that you get less direct sun, especially if you already have trees. I'm in a valley, and my northern slope holds snow days or weeks longer than the southern slope, so the growing seasons seems shorter than the southern slopes a stone's throw away
I didn't have a choice, but I would put the tallest trees at the bottom of the slope and get shorter as I go up the slope to maximize sun exposure.
Fruit trees are supposed to be happy on a northern slope, but I've only really had luck with mulberries & paw paws, after we added ducks and their daily water input. Doesn't seem to be enough sun for normal sun fruit trees.
Our place has an 1890 farm house with a ton of windows on the northern & southern sides. We gain a bunch of passive solar, which is great in the winter, but not so good in the summer. Would be quite nice to have deciduous trees between our house & the sun. Awnings over the windows at the perfect angle would also help in the summer.
Water running down the slope is an interesting challenge. Our soil stays much less moist than anything level nearby. Swales or ponds at the top our your property will help hydrate things downslope. Also, water storage at the top of the slope will give you water pressure at the bottom of the slope. Our house is at the bottom of our property, maybe for this reason
Most houses built on slopes near us get wet basements when it rains, but not us due the perfect placement of our driveway upslope from the house. I have added lots of features to slow and soak in rain, but the driveway is a great last line of defense for those big thunderstorm downpours.
We also have an old shed with a simple lean-to roof that drains upslope of the structure, which leads to rot...
Our north slope is perfect for mushrooms, and sounds like you will have plenty of logs for mushroom logs.
Do you have deer? They can make food forest establishment more difficult without a fence. I've been working on a brush tanglefoot fence around the perimeter of our property, and seems to bee a good low cost strategy the help keep the deer out.
Good luck & hope you post updates
