"Distinguished guests" or something along those lines

"Good evening folks."

"Good morning everyone."

Etc.

Includes everyone without being cumbersome. Less is more.

At a renaissance festival I once saw a performer begin her act by addressing the crowd

Ladies and gentlemen, and people too amazing to be constrained by the gender binary…

It's probably too casual for what you're doing, but I like "Guys, gals, and non-binary pals"

Comrades

“Theydies and gentlethems”

Dear humans

I've used "Hello Kings, Queens, and In-Betweens!".

"Folks" is good if you aren't in a very casual environment.

Bitches, bros, and non-binary hoes!

do you have to use ladies and gentlemen? what about - “sup yall”

"and those unaffiliated"

Listen up shitheads!

"My lords. My ladies. And everybody else here not sitting on a cushion!"

In what context in particular? Could "Everyone" work?

I usually go with "ladies and gentlemen, eithers and neithers". It's not fully inclusive, but has a good cadence!

Just say “hi, everybody!”

Ladies, Gentlefolk, and cool people.

Skip it and use "esteemed guests" or something

Ladies, Gentlemen, members of the Jury. Ladies, Gentlemen, esteemed colleagues. Ladies, Gentlemen, all yall Welcome aboard party people

Gentlefolk

One time for the Ladies / One time for the Men / One time for everyone in between, yes you need to leave them

Themtelmen

Replace it with "Esteemed guests" or similar, for the same level of formality.

Used to listen to a podcast aimed at helping you get to sleep called Sleep with me, and the host used to start every episode with something like "Good evening Ladies, Gentlemen and friends beyond the binary" which I thought was nice but I'm also soft for a bit of alliteration.

“Party people”

Just say "everyone"

From ladies to gentlemen. (Implies a spectrum)

Fred Durst already solved this issue. All the ladies, all the fellas, and all the people that don't give a fuck. Hot mamas, pimp daddy's, and all the people rollin up in caddies

The Queer Kiwi on YouTube uses "Guys, gals and non-binary pals.". Only watched two or three of her videos and I couldn't for the life of me tell you what they were about (I hope I learned something anyway), but that one phrase is currently living rent free in my head.

Were I to come up with something on my own, it would probably be along the lines of "dear(est) sapient beings", but it's in the realm of clunky, scientific, pretentious, etc. and needs work. Likewise, things like "esteemed fellow humans", read like an alien pretending to be human. The point being to include everyone with a single term rather than aim for two plus extra.

Im not sure there is one word you could lump "everybody else" into. Folks is generally pretty inclusive, "folks of all flavours" is a bit alliterative.

Ladies, Gentlemen and all the rainbow colors in-between'

Stole it from the Harley Quinn Show, from Joker specifically.

Themtlethem

Y'all.

What up m'people!

Gentlebeings

To quote Kelly Mantle "Ladies and Gentlethems"

Fuckers

"Attention, all fairy tale things."

Dreamers of all ages

My last boss just said “Hello, friends”.

Ladies and not-ladies.

why not just replace it with everyone? good evening everyone. attention everyone.

Hey ladies, fellas and everyone between

Folks, people, everyone, etc

...and Smizmars!

Folks

The classic go to is "guys, gals, and non-binary pals"

"Ladies, Gentlemen, and people named Steve!" /s

Real answer: "Humans" works on its own, or even just "everyone". Alternatively, I like "friends and mortal enemies"

When speaking to a crowd, sometimes I'll go "ladies and gentlemen, boys and girls, and everything in between..."

(I know "in between" isn't perfect, but it gets the job done.)

Earthlings?

It's funny at first I didn't understand it because you already had three words. But I figured it out in only like 10 minutes.

Themporers

I usually go with:

This is mambo #5!
