I think 2024 will make Advantage much more common. Especially in skills. The fact that a character can use both the applicable tool proficiency and the applicable skill proficiency, means skill checks can often be at an Advantage.
Advantage is an interesting mechanic. To be it feels worth about a +2½. In other words, if I have to choose between a flat +2 bonus or Advantage, I would take Advantage. But if a choice between a +3 bonus and Advantage, I would take the +3.
Advantage is great for making ordinary checks more reliable. But Advantage helps less and less when the DC challenge is more and more difficult. Then it is the flat +3 that can let one succeed over a DC that even normally impossible.
Additionally, Inspiration can grant Advantage, when the routine check must succeed.
As DM, I also plan to allow the use of a musical instrument to the Tool Proficiency for various kinds of checks, like Persuasion of a crowd. Amaze them and then as a celebrity ask a favor. Music can also help for some Medicine checks. And so on. I let get the players get narratively creative.
