I usually read BL omegaverse so I can only rec you that, no idea about straight omegaverse. Yuri omegaverse is rare to come by so I haven't read a lot over there either tbh. Anyhoo. i think depending on what you are looking to read about omegaverse, there can be two types of works in the subgenre.
one, romance-oriented and light-hearted. good to start would be:
Unromantic
Megumi and tsugumi
How my daddies became mates
Kowamote no Rinjin ga Ω datta Toki no Taishohou
Heat and run
Love shuttle
Unmei no Tsugai ga Omae da Nante
two, the slightly more serious and intense side of omegaverse with nuance, satire and commentary about the socio-politics of gender in omegaverse. like these:
Takatora kun to omegatachi
Shounen no kyoukai
Kakumei no α
Exclusive no love zone
You are my world
Restless webtoon
Double Fake
So yeah, that's all for recs from my side...choose and pick as per your preference.

ive never read any omegaverse or that other shit but i lowkey wanna see what the hype is about... so if anyone has like good recs plz ╥﹏╥ idk where to start
