Sharing/linking iPhones help

I have an personal iPhone XS, I’ve recently bought an iPhone 13 mini for work only. I want to share the calendar (I’m using Google calendar), photos, contacts and documents (Google docs, sheet etc). I only have one Apple ID & iCloud account and would prefer to keep to one account. However when I’ve set up the new phone up it’s sharing everything, all the things I want are shared but if I get/send a msg, make a call it appears on both phones, it’s also linked settings, for example I need different do not disturb times on each phone but if I change it on one it changes it to the same times on the other. How do I set them up so it only shares those selected things and they still act as different phones. Many thanks
