From the study: "Most devices (Fatigue Science Readiband, Fitbit Alta HR, EarlySense Live, ResMed S+, SleepScore Max) performed as well as or better than actigraphy on sleep/wake performance measures".

Great news.

The Garmin one is discontinued.

Also, is there a more "layman readable" version of this paper/report?

The Garmin watches have been replaced by newer versions with upgraded sensors. Garmin's tracking isn't perfect, but each version has made small improvements.

Yes, the study evaluates the accuracy, and the results are not good!
