Raid frames configured for all sorts of party sizes. I personally use KUI Nameplates but I did some rough setup on ElvUI's should you prefer those. Should also work on non-ultrawide resolutions, but will require moving some stuff around probably.
Icons shown on raid frames in the screenshots are this weakaura: https://wago.io/PersonalCDs
DPS/Tank setup: https://wago.io/BEjU9g9dE
^ Now deprecated as I've moved to using this config on all of my characters regardless of role.
Addons used in screenshot:
ElvUI
ElvUI Shadow & Light
ElvUI MerathilisUI plugin (will probably need for some datatexts + maybe textures?)
KUI Nameplates
Exorsus Raid Tools
WeakAuras
