The Courts and their "regional" powers (minor ACOTAR and CC spoilers)

Hi, I'm writing a fan fic and realizing that my understanding of the typical powers of members of each court is little inconsistent. Perhaps my memory is failing me. Can anyone clarify/help fill out the below list? Headcanon suggestions welcome.

🩹 DAWN COURT - Healing and ...a white light?

☀️ DAY COURT - Spellwork and bright light

🌚 NIGHT COURT - this is making me chuckle. How am I unclear on the Night Courts general magic strengths? All I can think of is Shadows. I'm not counting Daemati power as that's not a common gift.

💨 SPRING - Wind and Shapeshifting (do we know what Tamlin's shields are made of?)

🌊 SUMMER - Water (I only get this from Tarquins sheilds... and I guess Feyre's water wolves were from her summer powers?)

🔥 AUTUMN - Fire

🐻‍❄️ WINTER - I have nothing canon for Winter besides that they got some big ass bears but feel like it's safe to assume they have some Ice magic or something?

BONUS QUESTION: In CC3 the Flynn siblings have what they call "earth magic" and they can grow plants. Where in Prythian do you think that comes from? Spring seems like the obvious answer, though summer could be fun to?
