It's really difficult to find a plant to fit your criteria. Not many bloom in the fall. Some exceptions might be Winter Snowman or Winter Start Camellia, or a Hawthorne. Nandina doesn't bloom in the fall but the leaf color changes from green to a reddish color and the foliage of Starburst witchhazel changes to a bright yellow. Each of the shrubs mentioned grow tall and you can prune them to make them fit in your 4' wide area. Traditional flowering perennials for the fall include chrysanthemums, Aster novi-belgii (Michaelmas Daisy), Caryopteris (Blue Mist Shrub), Sedum 'Autumn Joy', and Solidago (Goldenrod). Garden centers typically have the best selection in the springtime so I'd choose the plants now and get them in the ground. Best wishes with your project!
