Treadmill sensor for FR45

My wife follows TrainingPeaks pace-based workouts with her forerunner 45 + Garmin foot pod.

For the treadmill she’d like to run Zwift. My non-runner understanding is that the Stryd pod is in-general more versatile and superior to the Runn or Zwift’s footpod options.

With the Stryd being useful outdoors I lean toward getting her one, I then wondered if she’d need to seek out power-based running plans rather than pace to make good use of the additional features versus a normal footpod outdoor?

Thanks for guidance!
