Not having one on hand I can't confirm but if the 6th and 7th Gen are anything to go by any in camera feature will work.
Features requiring Google Photos integration and usage however will depend on sandboxed Play Services.
Discussion
is there any update on cameraX extenstions being released with android 14?
Yes the extensions are now available in Android 14, however due to currently requiring 'Pixel Camera Service' and Native Code Debugging = On, it will be a little time before they're implemented into GOS.
Please be patient as we make the transition to 14 proper (Stable Release) at which point other considerations can be given appropriate attention and prioritisation.
