Category design help

Hi

I am trying to settle on the best way to develop my site taxonomies, have read a lot and searched for answers, but am confused on a general point

I am aware of Category, Tag and metadata structures and options but have this question.

Am I best to design a detailed Category approach, using parent child structure which would handle most / all of my filtering needs for page design:

For example:

Category 1 = Products – children = Brands
Category 2 = Features – children = List of features
Category 3 = Price Band – children = Specific Price Bands
etc.

Or would I be better to leave Categories for 1 dimension – say Brands and use metadata to structure other dimensions?

I am just learning to code and am able to do simple loops. My intention is to be able to design page templates that allow me to filter or select certain products to be highlighted on a page. Which taxonomy approach would have advantages for this?

Thanks in advance
