So, if you read my comment that you were responding to, you would have known that I was specifically referring to the washed out FBI plot, not the other things you mention.
However, while there was some movement on those fronts that you mention, it wasn't that much. Soong got exposited upon (using the always lovely telling rather than showing style of storytelling) a few details by the BQ about an alternate future. Core learned of her nature, which advanced it ever so slightly from the previous episode where she had already uncovered her "sisters."
No, Q's story wasn't advanced. We already knew he was sick and in very serious condition since the very first episode. It was reinforced multiple times already. When he tried to influence Renee and the magic bottle summons.
Raffi, 7, and BQ really didn't advance much. We only learned that there was still a bit of Agnes left in the Queen, but that wasn't a surprise. We already knew that the BQ was working to take over Agnes and wanted to assimilate people.
So, lots of window dressing. But in actually, extremely little plot developments. Just a few added details here and there. Like Q isn't just dangerously sick but "fading away." We learn why Renee doing/not doing the mission affects the future--and not even exactly, just a vague thing about making Soong's work redundant.
