Automate Process to Filter out Offshoots of Objects

Hi all,

I'm trying to see if there is a process anyone is aware of to take objects that have a few long skinny sections attached to them and eliminate sections that are less than a specific width. I have tried a few methods like filtering out objects with a low ratio of area to perimeter, and also have seen that there may be some success if I am able to convert the objects to rasters and then shrink them. I've attached images of and an example manual trim I did for reference of what I am hoping to automate.

Appreciate any help!

I don't know if it's a bit simplistic, but something like getting the centrelines of the polygons:

then buffering the result by a specific width, then removing any original features which are contained by the buffer.
