Yeah I think the strength of the show was how it handled everyday life for people in the setting and not necessarily the grandiose speeches. What they should take away from it is:
*More subtle writing that takes a little bit more audience inference and has some mystery to it without spelling everything out.

*More of an attempt to cover areas in the setting that don’t fall into the typical mold WITHOUT resorting to a pastiche of some other genre. Not “let’s have a Godzilla episode” or “let’s have an homage to this specific western/samurai movie”, but “let’s show this guy eating cereal with his nosy mom and worrying about his career.” It’s difficult to do without making it too mundane and boring, and I think they failed at it hard when they tried to do something similar in Mandalorian season 3 because it was so incongruous with everything else.

*Practical effects, props, and especially sets with a priority for shooting on location where possible. It’s okay and often better to re-use the same sets several times as you get familiar with the place.

*More attention paid to casting. The existing characters (Cassian, Saw, Mon Mothma, etc.) had already been cast elsewhere but all the new people fit their roles flawlessly. Even minor characters were more memorable because of the casting.

I think they might take the wrong lessons away, like feeling an obligation to a “dark and gritty” tone, morally gray characters and actions, or focusing even further on the already saturated period between episodes 3 and 4.
