What can I gift my partner (23m)? Posting it here because his taste resembles men over 40.

He works in corporate and is pretty workaholic. He uses quiet luxury but is down to earth and doesn’t care about material goods at all. He’s just raised that way. I’m great at gifting and prefer things which have a deep sentimental value and thought attached to them but I have no idea! His birthday is in 3 days. So men over 30s, what would you prefer to get from your SO?
