Then, you have your normal set of entries (whatever normal is for you
). The system decides what is in that list. Not something that you have direct control over, as far as I know.
Some will always be either not important to you, or not valid to you in your particular setup. There's nothing inherently wrong with that, there will just be items in the Open With list that you won't use.
You CAN decide which apps are the default for particular document types, with the Open With menu in the Get Info window.
Select your document, whatever it might be, then Get Info, and click on Open With dropdown. Choose your desired app from the list. Then, click the Change All... button. Then, double-clicking any file with that file type will default to the app that you selected as a default. And, one result of that, you may look at that Open With list much less often, unless you need to change to a different app for some reason.
And, there's other work-arounds, too, such as dragging and dropping files on top of apps. No need to go through Open With menus then, either.
