Yes, please use caniuse: meter. We should never link to the BCD-derived entries starting with "mdn-" as those are just the BCD data in another form.

The BCD data here looks fairly messy and implausible. I don't believe that the <meter> element and HTMLMeterElement interface shipped at different times, at least not far apart.

The Baseline low data ends up being defined by Edge 18, and all of the ≤18 values in https://github.com/mdn/browser-compat-data/blob/main/html/elements/meter.json. That will need fixing in BCD before we can add this feature.
