Go to the Houzz homepage and set up an account (free). Begin looking through the Ideabook section for photos you like. Put them in your own personal Ideabook with notes about what your favorite element is in each picture. You can make a separate Ideabook for each room of a house, one only for windows, and so on. You can also choose photos from the "photos" section and the "products" section.
Look through your ideabook(s) and find any common themes, or colors. Use these when talking with your architect, interior designer, and landscape designer.

tipi is right. We just finished out new house a couple of months ago and I must have 100 photos from houzz. I ended up saving mine on Pinterest as I found other elements that weren't on houzz as we progressed. Under Search, and Photos, put in some of the elements you just described (individually) and maybe use "Eclectic" as your style.

Yes, looking through photos and saving the ones you like will help you narrow down to a design style that you like and would like to live with for a while.
