My wife opted for the 40mm Garmin Venu Sq 2 ( https://www.garmin.com/en-US/p/801643/pn/010-02701-00 ), which is one of their smallest watches. More expensive, to be sure, but the battery life is way better, the software is good (instead of sucking like the Fitbit app), & I know of at least five (5) people who say their Garmin has lasted for _years_, which isn't something I can say for either of the Fitbits we owned.
The one knock against Garmin is that their pricing for watch bands is INSANE. Do not under any circumstances pay the money for the bands they're asking for; there are plenty of better, cheaper third-party options available on Amazon, Etsy, & other sites.
And to save you the trouble: the smallest watch that Garmin makes is the 34mm Lily ( https://www.garmin.com/en-US/p/698519/pn/010-02384-03 ). The main reason my wife opted NOT to buy the Lily was that the "stylish" patterned lens -- the background -- is distracting & non-customizable.
