Hey Adai, welcome! This is a big question, and a great one. There’s a lot of modeling best practices out there, but I’ll kick off the conversation by providing @fabio’s “Opinionated LookML & SQL Style Guide”. If you haven’t seen it, it’s a fantastic resource for making sure your model is tidy.
It’s not as high level as the examples that you’re curious about, so there’s still lots of room for others to jump in with their own opinions!
Sharing some of your own ideas and opinions, however loosely held, could help kickstart the discussion as well.
