Welcome to the board Buddy birdlover we're glad you found us
And congratulations on your new space!
Do you have the space to move your tiles around and try several designs before you decide?
Are the tiles easy to cut?
You could begin with a grid shaped like your floor and play with shapes/designs you like before committing. On paper, or with software
This web site has a few ideas to get you started:

Some shapes are classic ....like a LBD (little black dress) maybe pick something you are most likely to enjoy for many years.

you could start with a center design, and "frame" it with a border design....so many options - it's all about your preferences
have fun!
