Can you stand further back and take a picture of the entire facade and post it please. Based on what I can see arched doors may not fit architecturally

I would just leave it open! Plant a nice mix of flowers and bushes and you'll have privacy and a green landscape view from those front windows.

It looks like two of the arches have steps. The arch with the door looks like it is missing a lightbulb on the opposite side to the stair light that is lit up (first photo). If you like the walls' beige color, you could emphasize the arches by painting one side or the other or just the interior with one shade lighter beige. I don't think they actually need any emphasis, but if you are planning to repaint the walls anyway, this would be a good time to map out which walls will be which color.

I use custon solar shades for arched windows of they are installed inside mount with tiny little pegs . I need to see your windows to hazard aguess as to what you are doing.I get many solasr shades from Steves blinds and have used a guy to cut and build a custom light weight frame those shades are really permanent and then I handgdrapes from just below the arch all across the wall but I need to see your issue. Post the pic here in a comment DO NOT start another post .
