Beginner seller looking for advice

I’ve been looking for items off and on for a few hours now and it seems everything is either restricted or need approval. Can anyone point me in the direction of items that aren’t usually restricted, if you have a UPC code that would be even better.

Also, I figured this would be simpler because I’m not trying to sell big Nate items. I’m trying to sell things that usually go unnoticed in our desirable like under the sink organizers and drawer dividers just items like that.
