If you want to get listed, you will need to find a small category with an active editor where your site actually fits. Most categories have an incoming queue of dozens if not hundreds of sites that nobody is looking at. The only chance you have of getting listed is to find a small category where the editor actually keeps up with the flood of submissions.
Of course, even then if that editor feels that your submission is not a great fit for that category, they will move it to a different category where it may never get reviewed.
Submitting to a larger category is a waste of time. Anything within two levels from the top is not going to have editors that ever look at it.
When submitting your site, make it easy for the editor:
Only submit your home page.
Write a description of your site that is a full sentence.
A list of what your site does is appropriate for your description.
Avoid "marketing speak" like "visit now".
Avoid superlatives like "best".
Avoid the phrase "and more".
Make sure the description differentiates your site from the other sites that are already listed.
