I have Citlali and barely scraped through to getting it only thanks to a F22 clear (how?!) on day 2 and being able to leave days 4 & 5 at F19.
I definitely ended up using her a lot in my clears, even where I wouldn't normally:
Day 1: Kinich/Kazuha/Benny(C5)/Xiangling(C6)
Day 2: Arlecchino/Kazu/Citlali/Benny
Day 3: Wanderer/Furina/Faruzan(C6)/Benny
Day 4: Arle/Xilonen/Benny/Citlali
Day 5: Neuvi/Furina/Xilonen/Citlali
