The Quantified Scientist has tested a while buttload of smart watches against a chest strap heart rate monitor:

Apple Watches are at the top, but there are many other watches that are almost as good.

Is there a searchable text version of this resource?

In the video description click on "Show transcript".

But it seems each video is about a different model; having to search N transcripts still isn't optimal.

He's not written books on the subject. You can setup a search yourself. There's also a blog with easier access than transcripts. https://www.robterhorst.com/post/apple-watch-ultra-2-vs-seri...

Not sure, but every video shows a huge graph with all of the watches on it, ranked by accuracy. If you just view the latest video you can get an idea of the best watches, or where a watch you might be looking at falls, then you can search for the specific video where he tests it to see specifics.
