Hello, Ruinthel!
I see I’ve mostly already been beaten to it, but I missed some guilds that also take Night Elves/druids, so I figured I’d still post and compile a handy little list.
The Nightblade Sentinels
First off, there’s <The Nightblade Sentinels>:
The Nightblade Sentinels is a cadre of female only Sentinels that adhere to traditional kaldorei values and practices. They live to serve the Goddess and her people, primarily as protectors and as an instrument of vengeance against the foes of the Kaldorei.

Hand of Cenarius
Second, there’s <Hand of Cenarius>:
Set up shortly after the fall of the Burning Legion, the Hand of Cenarius is an aggressive order of extreme druids who would see nature’s balance protected from all threats at all costs. They go to great lengths to deter whatever defiler they come across, be they Horde, demon or undead.

The Myrmidon
Third, there’s <The Myrmidon>, essentially Kaldorei/Worgen privateers:
The sea beckons to those with the heart to brave its many perils. The Myrmidon, a privateering vessel under the guise of a respectable Darnassian merchant trader, is one such ship to hear the call in the Goddess’ name.

Moonlight Embrace
Fourth, there’s <Moonlight Embrace>. They’re an umbrella guild that covers all of the aspects of Night Elf society and more. They’re very centered on vengeance.

Court of Dawn
Fifth, there’s <Court of Dawn> - they seem to be more of a house focused Night Elf guild.
On a small island in the vast ocean of Kalimdor, the elven kindred are restoring buildings and homes, planting seeds and aiming to create a safe haven from the rest of the world.
In the estate of Zin’belore they gather, the refugees and elven kin who lost so much already.
Together with the Worgen who embrace the curse and use it to their advantage, a new culture is developing with the nobility and ways of old yet with knowledge of the past and sworn not to repeat history.Forum link: ( Elven, Worgen RP) Court of Dawn
Handmaidens of Elune
Sixth (this list is becoming longer than I anticipated), there’s <Handmaidens of Elune>:
The Handmaidens of Elune are a circle of women devoted to their Goddess and to the preservation and perpetuation of her teachings. First formed to aid in the war against the Lich King, the order flourished as a group of healers and teachers, but also warriors, an arm for the Goddess to reach out across Azeroth and beyond. With the Burning of Teldrassil though, came tragedy, most of the order lost during their efforts to aid in the evacuations.

The Last Court
Last but not least, we come to <The Last Court>, a guild seemingly focused on the more progressive stance of the current Highborne.
What started as a community meeting for Highborne roleplayers has naturally evolved into this guild: The Last Court. We’re Highborne lead and focused, but not exclusively so. We take onboard Kaldorei looking to learn the arcane arts, veterans of the Resistance, Rooksguard and Moonguard, those with ties to the nobility of the old empire and their sons and daughters.

As one last thing to notice, there’s also social events where you can check out current guilds - the current up-and-coming event is on Friday the 21st: Jurina’tore - The Great Hunt.
I hope you find something that caters to your taste!
