Enduro but smaller?

I really love the Enduro 3; looks, solar, mips, price. But the size is a no go for me, way to big.

The instinct 3 is a little to “tactical” looking. Seems like it would be alittle to chunky for sleep tracking. The Fenixchecks a lot of boxes too but it is a little too spendy.

Also looking at Venu4 and Forerunner 9/5 70 47mm

Seems Garmin has perfected their lineup. What would you suggest? Buy one, cry once, and get the 47mm Fenix Solar?

Main goal is battery life and health tracking.
