The gmic gimp plugin http://www.gmic.eu has an interactive FG extract filter that works well with clean edges or if not too clean can make a mask you can use with a layer mask. A couple of other filters in there as well that can make masks.
The Gimp threshold filter can often generate an image that can be used as a mask
Zip around a FG with free select or scissors or quick mask and use the selection to create a layer mask.
As you guessed, a layer mask is your friend
