Hi all, I would like to customise the way the collection is laid out

I would like to show
- Objects
(Meta data will exist on each Object to do with the object)
- Themes
- Locations
Each object will have a theme, and a location attached to it.
Users will search by theme/location/object depending on their interest/search query
The collection is organised by theme
I can't find where to change the base elements, I won't need most of these:

However I am aware that there may be a better way to set this up within the system. Could someone advise/guide?
Looking forward to hearing from you
