Welcome to the Forum, thanks for your Post.
It is always best to upload a Fusion f3d file, that way antone looking into things can see what settings have been used, to upload an f3d file go to :-
File > Export > Select f3d Format > Save to a location on your computer > Then attach to your reply.
There is a lot of work needed Editing the Sketch to get selection to work better, see attached file for some examples of one small edit that allowed the whole outer profile to be selected.
No idea if you want the cuts inside/center/outside so just did what I thought might be OK.
Re Quality, if you have set the correct settings as per your table then I think that Fusion will output the correct code and after that it will be down to learning the Machine 🙂 🙂 Hope the attached file is of some help 🙂 🙂
I have no errors here so without your file I don`t know what has been done to produce these errors 🙂
In the image below is an example of an edit, the line shown is been changed from on line to two shorter ones by using the "Break" option under the "Modify" tab in "Edit Sketch" mode.
