iPHONE's contacts

I bought this new iPHONE XS MAX in November. Having never had a smart phone before, after 4 lessons in the Apple stores, I still haven't used it, except to try to photograph pics and videos on it.

Since my family died I have been switching from London to New York, so what I wanted from this phone, was:

1) to use one mobile, instead of having a flip phone, here and another flip phone there, each with respective contacts in the US and the UK.

2) to be able to photograph and video and get it onto my Macbook Pro, now in El Capitan.

3) to be able to show show videos and photos on the iPhone that are on my laptop. --Kind of like on  an iPad.

4) to be able to talk into the iPhone and the get it typed onto my laptop, as the OCR on the iphone is better than on my 2012 Mac.

5) I do not want to sync my 1000 GB macBook pro hard drive with my 256 GB hard drive on my iPhone!  In fixing my Calender the Apple tech introduced my to iCloud, that I really didn't want to use too much, as my digital life is complicated enough. And I certainly do NOT wish my 65,000 emails on my icloud and phone.  . . . .  So in fixing my Calander after upgrading from Mountain Lion, all my Many Many contacts are on my phone and on iCloud. 

PS: I do not want to scroll for ever, as all my notes in my contact book are now on iCloud and iPhone. I only want NAMES with their PHONE NUMBERS on my iPhone and in my iCloud.

All this to say, HOW DO I ONLY HAVE NAMES AND PHONE NUMBERS ON ICLOUD????

I took my Contacts out of iCloud and the suddenly I had no Contacts on my Computer. So of course I reinstall the contacts on iCloud. I really don't want all the info I have on my Mac in Contacts on my iPhone. I rather then put all my contacts in one by one.  ..  

But how do I then not loose ALL the INFO on my Laptop in Contacts. (Ir is just so convenient to have notes and important quickly accessible info in my Contacts. 

---ANY SUGGESTIONS would be greatly appreciated.

Best,

Prima
