F2 recovers and throws 1) to first in time to put out the batter-runner, 2) to first and over the head of F3, 3) to third in time to tag R1, 4) to third but not in time to tag R1.

That's not batter interference, but rather interference by the batter-runner. The ball is dead immediately, BR out, other runners return. 8-4-1a
