I use very few folders. My personal notes such as journal entries are primarily in the root of the directory. Folders are for everything else. These are the folders I use:

Attachments for images, PDFs, etc
Clippings for articles and other pages captured with my Web Clipper
Daily for my daily notes, all in YYYY-MM-DD.md format
References for anything that refers to something that exists outside of my vault, e.g. books, movies, places, people, podcasts, etc.
Templates for templates. This is actually nested under "Meta" in my personal vault, but I've moved it to the top-level for clarity. Meta also contains my personal style guide and other random things that are about the vault.

Templates and metadata

The .obsidian/types.json file shows which properties are assigned to which types.

Most of my properties try to be useful and reusable across categories
Many properties have short names e.g. start instead of startdate
I use the list type more than the text type for many properties, because I find it useful to be able to enter multiple links

Categories and tagging

I primarily use the category property, e.g. category: [[Movies]] to organize and navigate my vault. Some rules I personally follow:

Always pluralize categories and tags
Use YYYY-MM-DD everywhere
Never use folders for organization
Single vault for everything
Avoid non-standard Markdown

Rating system

Anything with a rating uses an integer from 1 to 7

7 — Perfect, must try, life-changing, go out of your way to seek this out
6 — Excellent, worth repeating
5 — Good, don't go out of your way, but enjoyable
4 — Passable, works in a pinch
3 — Bad, don't do this if you can
2 — Atrocious, actively avoid, repulsive
1 — Evil, life-changing in a bad way

Why this scale? I like the 7 scale better than 4 or 5 stars because I need more granularity at the top, for the good experiences, and 10 is too many.
