Something you might try is to move the chairs and the mat over to one side of the area to create a conversation area, as an experiment. If you like the way that looks, you could think about doing that on both sides. Start to look at both sides as two separate ”rooms” and think if you would actually enjoy sitting out there. You have so much stone out there I wouldn’t be afraid to bring a big standing candelabra for candles. You need to be careful not to clutter the space. You could have one side with seating and the other side with trees and other huge plants in containers, like a rooftop garden. Maybe you could even create a water feature with water spilling down a metal piece in front to the wall. If you get enough sunlight on either side, growing night blooming jasmine on trellises could work.behind a seating area and become a fabulous place to sit for drinks in the evening. But I wouldn’t do it as a stage set. Only if you really would like to use the space. Otherwise, I would treat it as a gallery-museum type space. Be very careful where you place an object or plant because you will be framing it and everybody is going to stare at it, so it better be worth looking at and like it belongs there. I think your entry is amazing!

Two good answers above but...what will you use the porch for? Will you really sit out there? If not I suggest you add some potted plants and a wreath on the door.

Whatever you like really. But if this is your front door, from a practical standpoint I'd focus on spending time and money installing some type of walkway from the driveway to the front door. Looks like this might be a new build? Even wood chips bordered by rocks or landscape timbers would be better than just dirt and grass, particularly when it gets wet. Seems like the cheapest easiest thing would be cement . . . But I've even seen walkways done with pavers surrounded by ubiquitous red mulch and landscape timbers to keep the mulch from traveling. Depends on your budget and taste. Then landscape with something colorful along the garage. If it gets sun, you might consider rudbeckia, that's what we had along our garage side. Maybe mixed with some colorful orange asiatic lilies for a red, yellow orange theme. Or even coreopsis, another easy peasy perennial to add a lot of seasonal color. Some little golden globe shaped arborvitae or a dwarf mugo pine for winter interest. Again, what's common and easy to find around here (I live in your zone). That's what we had. Depends on what you like. Another stunning combo is the pines or dwarf junipers mixed with bright red landscape roses. That's what we had along the entrance walkway of another place I lived. Vinca as a groundcover below. Then keep it simple on either side of the doorway, just buy something pretty already made up at the big box store that fits the light conditions. Don't overthink it. Maybe a bench if you like to sit out there. I have a bench outside our front door where I can rest after weeding the front garden. But focus on the path leading up to the door and it's functionality as far as providing snow and damp free access to your front door . . . hosta are good if it is shady along the garage. That's what my dad has, with some small yews. If you have deer though, yews will get eaten, as will arborvitae. Stick with junipers or pines or dwarf blue spruces . . . there is a juniper shrub called "blue star juniper" that is a very popular foundation plant. The blue spruces, unless you get an extra small one, tend to get too big eventually. Other great small foundation shrubs are "wine and roses" small weigela or "magic carpet" small spirea. Or "goldstrum" if you like yellow foliage. Another one is Mt. Airy dwarf fothergilla, I see that one a lot around here.
