You can run some metal raceways to the 1st (AFCI) outlet in a metal box.
It apparently doesn't have to be max 6' from the panel anymore.
I still haven't looked carefully at "where". My impression is AFCI are
required about everywhere a GFCI isn't.

The double pole breaker would have to be AFCI (which may be what you
intended) unless the multiwire is in raceway as above. The intent is to
protect the whole branch circuit.

There is a fine-print-note for smoke alarms - I believe hard wired smoke
alarms on AFCI circuits are required to have battery backup.
