That is how we do it. Some major purchases I get a small say in, like sofas. I’m forbidden from buying lamps. The rest is up to her. Sometimes she asks me to build stuff (I do woodworking in my spare time) but that’s it.
I have total aphantasia so I can’t imagine a circle, much less a room. I’m in awe of your abilities.
If the husband has a strong preference then we make it work, he wanted windows without the split panes, big picture windows, I had a weak preference for the more vintage ones we had but did want the storm rated efficient ones so when we got them he chose and they are great.
BTW, I am never sure if I’m actually visualizing like literal images in my mind, it’s not really like that, not seeing in a literal sense. Slightly different sense of knowing. I do dream visually usually though (like asleep and dreaming), literally see and hear things in dreams so know my mind can do it.
