Looking for a model fortigate compatible for GCP Interconnect

I am not sure. My project is to build a dedicated or partner Google interconnect from Onpromise site. So i have to choose a model that work perfectly with Google interonnect. If you say any model will be compatible that means you are far from the  right answer because at least the fw must handle 10Gbs connection which is not garanteed by all models you must revise those configurations not only the soft capablities.
