If you go to a lighting supplier they can show you catalogues of exterior lighting fixtures. Many of them come in "suites", which means they are all the same material and styling, just in different dimensions and proportions. This allows you to choose the size you need for each location, and they all go together. It's possible to mix and match, but you'd have to be a very talented pro to do it and I wouldn't recommend it unless you absolutely have to. Congrats on your new house!
