A short list you can actually use
Reach and impressions: did anyone have a chance to see it. Views: they started. Average view duration and completion: they stayed. CTR: the package earned the click. Saves, shares, and comments: they did something. Returning viewers and followers gained: they might come back. For live shows, average viewers, peak, and unique chatters.
Revenue per viewer, RPM, and CPM are money metrics. They are noisy and they are not a moral score. Look at them monthly, not every hour.
