Several different ways to extract a foreground other than the scissors tool. As
you say if the background is complex then the colour or fuzzy select tools might
only do a partial selection. But that might be enough combined with the quick
mask to paint in 'missing bits'. You should also consider using a layer mask to
the same effect.

Then the paths tool, often overlooked, but for smooth edges gives a good
selection. A bit labour intensive.

The most automatic is possibly the foreground select tool.

Made my rough selection around the area and painted in the area.

Gives a selection like: https://i.imgur.com/GVImhkI.jpg

But that is not the same as an Auto-Crop: https://i.imgur.com/SXk44fG.jpg

There are plugins to assist, in particular I find the g'mic plugin www.gmic.eu
with interactive foreground select useful.
