I find it super weird that the only time we see any in-universe ads (not counting Lower Decks) it's:

• A dead planet where an arms dealer used to operate and their holographic sales program was still running
• A single TV ad made by Quark on DS9 (that he illegally broadcast by hacking the communications system or something)

I would think that every Ferengi ship would just be a giant holographic billboard for Ferengi products and services. We even see Ferenginar a few times and there are no ads anywhere. Not even in the FCA building. But they do make a point of showing off how you have to pay for everything; including visiting a person's home.
