While we’re on the topic of additional lines that might warrant some tweaking, I have a few contenders:

Rey’s line about “I will earn your brother’s saber…someday.” There’s never been any indication that she felt unworthy using the lightsaber in the previous two movies, and she doesn’t end up “earning” the saber at all; it’s just handed back to her five minutes later. Also, Rey ends up using an entirely different saber in the finale? And she gives Luke’s to Kylo? (The only rationalization I can think of is that it’s subtextually foreshadowing “Ben will earn your brother’s saber”? But that’s unbelievably messy, even by this film’s lofty standards.) I dunno, it doesn’t make much sense. It’s another “Rey, I never told you- Blurgbruglbgrub” - They set something up, and then they forgot to pay it off. Maybe Rey could simply say “Here,” as if she’s just “hanging up” her weapon after practice? Or reverse the footage - Leia gives the saber back to Rey as a show of encouragement? (Implied that Rey gave it to her after the training course out of frustration.)
Trimming around Hux’s “I’M THE SPY!!” “*WhAaAaAaAT???” ThisIsCreation had a really solid idea for this on the Redux thread. It’s like “You were a spice runner??” to me - out of place humor that breaks what should be a tense moment. (I know I lost that argument, I’m not trying to restart it.)
“Leia sensed the death of her son at the end of her Jedi path.” So she decided not to pursue being a Jedi, which resulted in…the death of her son, her own death, and the rise of the First Order and the destruction of the New Republic at the hands of her son? Way to go, idiot, you played yourself! If Luke just says “She sensed ‘death’ at the end of her Jedi path,” it’s at least vague enough that we can assume the alternative future would have been even worse.

Script is whack, yo.
