I always end up in decision paralysis because I think of way too many possibilities. Is there a way I can avoid brackets? If I am able to drill into studs should I just use normal wood screws? I'll be using it as a tea/spice shelf.
Screws into studs are always best when possible. Get yourself a stud finder. Even a basic one will do and they are super cheap these days. Like, less then $20.
If you can get to two studs, wall anchors are unnecessary.
