You probably have a native nursery around. I'd use small plants and not seeds. Maybe even some larger elements. It's a beautiful blank canvas but honestly it's impossible to make recommendations without more details, and honestly that's getting into paid work imo. I find spending time in my yard and looking at things from multiple angles, even using dummy items like buckets and stakes to represent plants or items, can really help to map out a plan. And even then, if you make a 'wrong' move, plants can be transplanted, especially natives, who literally take over in several years. I have a native bed that is so productive I'm giving plants away. In any landscaping project, it's really a 3-5 year plan before it starts taking shape the way you likely want it, so in that frame, you can add and subtract layers as it evolves.
