IM promotion. How to form a CNC?

Question

Search Engine Optimization

Good afternoon! The question arose of how best to make CNC ....
There are categories of goods
Product catalog /catalog/category1/category2/brand/
Brand catalog /brand/brand1/category1/category2/
In general, you can get to the page with the list of goods from two places ... The
question is the following for the product card, how best to make CNC:
1 - in the catalog /catalog/category1/category2/brand/PRODUCT_ALIAS/
in the brands /brand/brand1/category1/category2/PRODUCT_ALIAS/ (with a canonical link to /catalog/category1/category2 /brand/PRODUCT_ALIAS/)
2 -
in the catalog /catalog/category1/category2/brand/PRODUCT_ALIAS/
In brands /brand/brand1/category1/category2/
All links go to product cards from the catalog /catalog/category1/category2/brand/PRODUCT_ALIAS/
3 -
in the catalog /catalog/category1/category2/brand/ link to /product/PRODUCT_ALIAS/
in brands /brand/brand1/category1/category2/ link to /product/PRODUCT_ALIAS/
I saw all three working options on different top sites and can't decide how best to do it....HELP
