Confusion around node lifecycle and best practices documentation

[WillaWisps]

Your Godot version: 4.2.1

Issue description:
Coming from a background of react web development, I would love a page on the lifecycle of nodes, especially with regards to best practices around _ready() and when nodes become visible to the eye (rendering) in the viewport.

Some questions I have:

• From print statements and breakpoints, it seems like nodes become visible as they enter the tree (_enter_tree()). But if I pause with a breakpoint in Parent A's _ready() function, I don't see Child B rendered in the viewport, despite it having visible == true. Does this mean the rendering of children waits for the parent to be ready?
• Are there any pros/cons with changing reusable Child B's variables in Parent A's _ready()? Say we want to change a variable called "color" of Child B from red to green because this instance should be green. Is there a frame where Child B is "color" red if we change "color" in Prante A's _ready()? Would it be better to listen to the NOTIFICATION_PARENTED notification (which should happen as the node enters the tree if the nodes are setup by the local hierarchy and not a script) and change the variable instead (maybe bypassing Child B being ready with the incorrect value)?

Potential pages where these changes could go:
