Best beginning watch?

I want to buy myself a new smartwatch for:

• Exercise (Edit: Mainly Hiking, running, boxing (if possible?), workouts (bodyweight)(what would you track?)
• Stats (sleep, HR, etc.)
• Music control via my watch
• GPS (for when i go on a run)
• Not too big since I don't have big wrists

Budget is about 250$CAD

Thank you in advance!! Also, I am with Android (Pixel 8) if it changes something.
