In case you haven’t seen it already - 3mdeb shared some info on the state of things during last FOSDEM. If I’m not mistaken they also did an update the year before too.
I know of exactly 1 AMD corebooot laptop. Starlabs Starfighter.
For coreboot you’re basically on Intel. As others mentioned, look up dasharo. They have added support for two modern MSI motherboards and Intel cpu models.
