As far as a panel change goes this would be a very uncommon code.
Most every place I know and have heard of does NOT require AFCI breakers for a service upgrade or panel change. The AFCI requirement is for the branch circuits. Replacing a panel is NOT altering the "branch circuit".
If you alter or extend a bedroom branch circuit, then you are required to upgrade to AFCIs, IF
your area requires them.
BTW Triple, why do you limit yourself so much on these circuits? And how do you determine the "800 watts"?
