You haven't mentioned whether you want to make large prints or just want to show your work on the internet. If you are going for large prints then you will want something like the Sony A7r ii, or the Nikon D850, or the Canon 5DS R. On the other hand, if you are only going to display your images on the web or on an HDR TV, a cell phone will do, or any crop sensor camera.
The OP did ask about "full frame" options. A cell phone is not in that category.
