No watch has FDA sanctioned BP monitoring. Dont count on any claims or marketing to the contrary. One would be insane to rely on a watch with current technology.
With that said any new version of an Apple Watch will do the same functions. Lets say if you want to be current nothing older than Watch 9
For all practical purposes that it makes sense with the latest Watch 10/ You will most likely charge it every day though I suspect you can wring two days out of if with the best settings.
I used to freak out about this, charging the watch is a HUGE NOTHING. I assume you take showers

well then, drop the watch on the magnetic charger and go take your shower. When you get out of the shower or within a few minutes depending on how run down it was. The watch is charged and put it back on your wrist. Sleep with the watch on, as the watch will keep tabs on your heart rate, respiration rate, how long you were sleeping and what stages of sleep you were in. The graph will even show what hour or minutes you woke up and went back to sleep, even going to the bathroom .
A man of your means might like the Apple Watch Ultra 2. more robust, can go deeper in water then the Watch 10. Battery like will be up to 3 days without charging (but charging is a HUGE nothing on the watch 9 or 10) The Ultra watch 2 can only be bought with the built in cell unit for a separate phone number. Not that you have to use it. Im unsure about what other features it may have but I suspect it will take a year to learn all the features of the regular series 10 which if you want can also be bought with a cell unit to use its own phone number. If not, everything works through your cell phone.

It will take you forever to learn all the robust features, however for everything you mention here is a no brainer. I still find cool functions after years of a Watch 7 and now a Watch 9
Heck I just realized it even tells me the amount of time I was out in daylight! Blood O2 is also cool. Wrist temperature, lets say you think you maybe getting sick. The wrist temperature doesnt give you a reading, it will tell you if your temp is above or below your normal. I found out last year when I thought I was getting sick (Covid) that the watch actually picked up the difference in temperature when I was sleeping.
Other VERY cool things are it monitors your sleep for all kinds of issues. Freaking amazing, I love the health functions as you know I had my issues, lucky I am retired now I can of to doctors instead of work *LOL(* no kidding, if your into health/technology and gadgets the watch is FREAKING awesome.
