Yes, window selections help to make the selection step go more quickly. I just timed myself and it only took me 12 seconds to finish the trim cleanup step. The end result should be the type of variable offset curve that you're looking for.

Also in some cases it may be easier to keep the pieces to keep in the Trim command rather than picking the pieces to remove - to do that set the option for Mode = "Keep" in the Trim options and then click in the middle area of the large pieces that you want to keep.
