New to me, Richard Rosenman’s $50 IK Studio – Inverse kinematics plugin for After Effects (February 2025). Apply IK to the joints of your 2D cutout cartoon characters. He also has a survey of The Best Rigging Tools for After Effects for 2D characters and props. Probably far easier to do such animation in Moho or Cartoon Animator. But if you have to use After Effects, this appears to fill a gap.
