From my perspective, that looks like an enormous yard. Hope you have fun with it!
Other people have done a nice job of laying out some pros and cons. It sounds like you have previous experience and know what you want to do, but I thought I’d share my experience starting to grow fruit in a small in-town yard (corner lot, 90’ EW x 70’ NS, several large city street trees, neighbors’ houses within 50’ of the property line in all four directions).
When we moved into our house about seven years ago, there were about three dozen yew bushes, a “burning bush” euonymus, an azalea, two holly bushes, a young Norway maple, and three large street trees (two sugar maples and an older Norway maple).
My wife hated (hated!) the Norway maple, so the first thing we did was put out a hit on that, with my dad serving as the “professional” (he was a tree trimmer in his youth). The tree was maybe possibly also a city street tree, but nobody ever said anything.
My wife also hated the yews with a passion, so the next thing I did was dig them out (by hand, which was pretty good exercise and kind of fun in a weird way). Several neighbors expressed their approval of this move, and as a matter of fact, the neighbors whose yard was screened by one line of yews were particularly encouraging. (But then they built a fence along the same property line a couple of years later, so maybe they had second thoughts?)
I wasn’t a fan of the euonymus bush, so that came out the next year. (At this point, one of the neighbors across the way said, kiddingly, “Looks like you’re just tearing everything out!”)
My wife liked the idea of growing (a) things that had flowers and (b) things you could eat. (Her parents immigrated from China, her family ran a restaurant, and her father, who is ninety, still grows a significant vegetable garden, so “there should be a practical and preferably edible purpose” was a big thing for her.)
And so, with virtually zero gardening experience, I embarked on growing fruit. Looking into things a bit, I stumbled across some pictures of espaliered apple trees. Showed them to my wife, she said, “We should do that,” and now I’m in the process of growing about sixty (?!?) apple and pear trees in the form of a couple of Belgian fences, one in a row along a south-facing street and another in a L along the north and east property lines. Also added a peach tree, an Aronia “brilliantissima”, and three Nanking cherries, and we’ll see what else.
At this point, the espaliers are still growing in, and the only thing I’ve actually eaten fruit from is the aronia (which I kind of like the taste of, actually). But even though the trees are still going through their young-and-somewhat-straggly stage, the Belgian fences have become quite the attraction/curiosity/conversation piece. Like, people who are driving by actually stop and stare at them. A number of people have asked me what they are, and a few people have asked how they could do that, too.
So, in my short experience, it seems like it’s possible to grow fruit trees in town and have them be a positive part of the landscape, just from an aesthetic/neighborly perspective.
That being said, one question that might come up is whether you are going to spray your trees. I’m keeping things absolutely as minimal as possible in that regard, because like I said, I have neighbors’ houses literally twenty feet from where I’m growing my trees, and even if I felt assured that it were safe, I don’t feel like it would be neighborly to spray anything ending in -cide (and I suspect that my neighbors would agree).
In the OP’s situation, if he does plan to spray, this might be a reason to keep the evergreen belt, because even neighbors who might be ok with having the evergreens replaced by fruit trees might not be ok with spraying along their property line. (And yes, I know that the neighbors may be putting God knows what on their lawns, but life ain’t necessarily fair.) With this in mind, I see a lot of merit in @disc4tw’s suggestion.
Again, hope you have fun with the trees, and enjoy your new home!
