After experimenting with numerous skeletal and motion retargeting methods, I've discovered a remarkably straightforward and effective approach using the Meta Movement SDK: Meta Movement SDK Documentation.
Released by Meta in Q1 2024, this full-body tracking algorithm provides comprehensive hand tracking, extends coverage to the arms, and leverages AI computation for lower body movement. Currently, by simply downloading the Movement SDK Sample for Unreal from GitHub Oculus Samples and installing the Meta XR plugin, users can immediately run the sample and directly capture animations using Take Recorder without any complicated setup.
