Smart watch help - trying to get something for a surprise gift for bf

My boyfriend started cycling last year and is getting really into it. He currently has a hand me down fitbit that he uses to track heart rate and overall health date. He uses Strava on his phone but it's constantly stopping mid ride and he doesn't realize it stopped tracking until the ride is done. The fitbit battery is starting to go out so I thought it'd be nice to surprise him with something new.

He rides outdoors, has a Samsung s22, and will be getting a wahoo kickr this winter. I'm hoping to keep it under $250.

Will a wahoo watch track heart rate and sleep data? Do the garmins track health data and work with Strava? Maybe another newer fitbit?
