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.
