I’m trying to fully understand the (up to) 4-layer example in your visual.
Layer groups are useful to keep parts of an overall image together and sometimes apply effects just to that group.
Gimp can use drag-and-drop to speed editing up, but everything is still in a menu somewhere. Your Layer Dock is essential.
this example: https://i.imgur.com/4HoleJM.mp4
Starting with your image open
Add a Layer Group
Add a new layer and that goes straight into the Layer Group
To put you image into the group by click and drag. Make sure it is under that new layer.
Color select the background color.
With the new layer active, fill the new layer with a click-drag from the FG color swatch into the canvas. (you can use bucket fill ....)
In the layer mode set to color erase.
For a new background, Add a new layer. It is in the layer group.
Drag it outside the layer group. Drop it to the bottom of the stack.
All sorts of ways to fill this, try click-drag from the patters dock.
Quote:it would be awesome if you could reveal some words bout the layer modes, transparency, and masks —
which seems to b somewhat the "secret sauce" in GIMP workflows.
Your friend is the Gimp manual. (sometimes) otherwise a search usually gets a result.
