When I was looking a couple years ago, most Garmins had at least 2 buttons, but only those with 5 supported music control via buttons.

I think I have used the pulse oximeter maybe 1x/year, and that's counting during COVID shutdowns, when people talked about pulse ox more than in normal times.

I will keep my Garmin and will use it when exercising. But I would never buy another one as long as I can get Pebbles instead.
