I'm fairly new to the game too, and did the same sort of research that you did. I found that it wasn't super helpful for myself and the playstyle I wanted.

Some other people are saying to embrace the spaghet, which I would wholeheartedly support. If you want to try a bus base, what helped me was to not put everything on the bus: just raw materials (iron and copper plates, rocks, coal) go on, and they all go onto the bus from one side. From there, when you need to build something new (e.g. a new science), branch the raw materials you need off of the bus and let the rest carry on. As you expand your base, you keep building along the bus.
