Trellises. I like these. They look neat and strong, you can use the number you want and space them out as you want. Take local advice on what to grow on them. http://www.gardenmetalwork.com/Trellis.htm

Well, creating storage niches is simple, then. Plan how big (wide and tall you want the niches. Presumably they will be less than about 14.5" wide (16" minus 3/4" times 2), otherwise you'll have to remove 2' x 4's. If it's a non-loading bearing outside wall you can remove studs; but check with an engineer or carpenter. It's likely load bearing if on outside wall. With the age of the house your studs may be farther or closer apart, too. You may also want to pack around the inside of the box (niche) with hard styrofoam insulation, which has greater R value than fiberglass. May also want to use canned spray foam to further seal? This way after removing some insulation you won't have as much of a cold spot on outside wall where niche is. There's a number of pre-made (pop-in) solutions like this: https://www.wayfair.com/storage-organization/pdp/wg-wood-products-bal-harbour-155-w-x-495-h-recessed-shelving-wgwp1493.html This example is interior wall. See here for a DIY: https://www.diynetwork.com/how-to/rooms-and-spaces/walls-and-ceilings/how-to-make-a-wall-niche Second approach, similar to above but narrower: https://www.familyhandyman.com/storage-organization/build-a-wall-niche/

I like several of the ideas presented, including the deck, assuming it won't face West while receiving evening use. Depending on circulation/traffic patterns, a couple of chairs with a small table between could be nice. All of my other ideas were landscaping related, since I love gardening, and think it's plenty fun all by itself, lol! <3 A small accent tree (6'-10' tall & wide) without invasive roots would also be really nice -- or a circle of tall, colorful hollyhocks (sorry, I always think of hollyhocks when I think of farmhouses) -- maybe surrounded by short, cascading herbs/plants in raised planters/containers. I wouldn't necessarily center the tree; it might look good off to one side, framing a view from inside the house. In addition to the tree, if you wanted to add a water feature of some kind (old fashioned water pump inspired, maybe?), it would fit better in the space if the tree wasn't centered. Do y'all have any hummingbirds in your area? Plants that attract hummers and butterflies are always awesome right outside windows. You could use shepherd's hooks with hummer feeders, too. Or, depending on which direction it faces, I'd consider a pergola bridging the gap between the bedroom and porch. If it faces North, then I'd skip the pergola, to allow maximum sunshine into the window. You could grow a controllable vine (max height of 20'; no roots/shoots/tendrils that will work their way into your house's structure) up the pergola's legs and over the top of the pergola's roof. I'm partial to roses, myself, but you could use other climbing plants that are more compatible with whatever "modern farmhouse" means to you/your area. :-D

You have a psuedo-dutch colonial. But it looks like the way it was constructed is as if there is a plumb vertical exterior wall which is what the roof bears on, and this upstairs vertical wall is in-line with the 1st floor wall (at least in back, probably in front but can't tell with the porch). Then the psuedo-look "slanted" roof was added on outside of this vertical bearing wall. If so, that would lend well to just removing this psuedo- shingled "slant" wall to expose the plumb vertical wall. However, it would be a lot of work and money, as you have to then sheathe the exposed wall, extend a soffit of some sort, and in front probably deal with a porch roof that may fall short of this wall. It would be out-of-pocket, not insurance money. You also have a nice E30.
