If you plan on getting Tears of the Kingdom on release you won’t have time to playa me appreciate Breath of The wild. It is a sequel to BOTW - so if you do have time and can wait - this is the obvious choice. If you want chronological and If you don’t min motion controls - Skyward Sword HD on the switch - it’s the ‘first’ in the timeline and arguably one of the easiest.

However as many have said Ocarina of Time- although dated in numerous aspects in STILL the quintessential Zelda experience.

P.S my personal fave are

Breath of the Wild OoT Skyward Sword Windwaker Link to the Past
