I live in a historic home so I have wicker and rockers on mine! Is it just for looks or will you sit out there? If you sit out there, you need something that is comfortable for you to sit in that looks nice too. The orange would work for all except Spring IMO. As to dirt, yeah, anything that is outside even in a covered area will get dirty. If you sit out there, two chairs and a table between to hold that drink would be nice. If it's just for show, the bench would work as well.

Your front door doesn't need to be centered in your front porch. Remove the bushes from and dig out the ground left of the sidewalk, tossing the dirt over to the right side. Build your front porch the same width as the cantilevered two story part of the home and at least eight feet deep with a forward facing gable roof with its point between the two windows. Use thick sturdy posts.

I ended up putting wreaths below the outside door lights. Like you I was very hesitant to put anything on the door. I do have window boxes under the lower windows. However with a covered porch nothing ever grew and they are messy. Water did not evaporate and the sun was never on them until very late in the afternoon. You might try hanging baskets over or slightly out over the railings. I put mine out from the railings so water wouldn’t drip on them. You have a beautiful home. Best of luck to you.

I think shrubs should be cut back or replaced with shorter plantings so that the front of the house is visible. Then consider reworking the porch. The decorative piece in the center of the gable looks distracting to me. Is there a walkway to the entry?
