Seasoned dev but new to local LLMs: help me pick the right Apple product for hosting model in the 27B - 36B size

Basically the title. I would appreciate guidance to pick the right amount of ram to run these.

Usecase:
- local code completion/coding agent
- reasoning and categorizing data using structured output.

My wish: i want a lot of actual context as i need to process large amounts of documents to inform my models categorising of data

Hope this is okay to post - i do not intend to violate the rules of this sub!
