Recently I was working with a Ubiquity system I also manage and was using their built in "heatmapping" functions. Where you can upload a floorplan and then see the signal strength proposed on it. I know you have floor plans but would love to see the ability to show they heatmap on it as well for planning and showing to customers before install.
We have a free (but separate) Wi-Fi Designer application that allow you to visualize heat maps on floor plans. Please take a look at https://www.cambiumnetworks.com/products/software/wifi-designer-and-wifi-inspector/
