I need a counsel about my websites' domain.

Let's say I have just bought two domains: xyz.com and xyzphotography.com.

As we can see, the first one is shorter but way less meaningful than the second one. The second one contains a photography keyword but it's longer.

I have only one website which is my photography portfolio. Can you advise me how to set those domains to make it all as SEO-friendly as possible? Which one should be the main one, does the rest should work on their own or have some kind of SEO-friendly redirect to the main domain?
