I have always liked the Trim and Extend commands in Autodesk Inventor, and now AutoCAD 2021 incorporates the same simplified behavior. As you might remember in previous versions, when using the Extend or Trim command in AutoCAD, you were always prompted to select the boundaries first. Now in 2021, AutoCAD detects the boundary(s) automatically, saving the step of having to choose one or more items before selecting the actual items to Trim/Extend. Another nice change, is that the command default to a fence selection, making it ideal for selecting groups of objects.
