Not really. Most consumer trackers are pretty poor. I remember listening to a sleep scientist podcast and they had found a 'sort of' consumer level tracker that was almost as good as their lab kit but it was still something like £1000 or $1000.
Here's some actual testing of consumer units:

Interesting, I’ll have a look at what the data says.
Re. Sleep tracking, do any devices substantially improve upon time in bed? Again my watch really struggles to differentiate between sleep and anxiety ridden ceiling staring.
