Here's the setup I've been using since Wrath. Obviously, things have changed over the years as addons come and go, but with ElvUI, I've been able to make and further refine it into my favorite iteration yet. Hopefully, I can get this same look and feel in Midnight. If not, consider this post a eulogy.
The top bar is provided by WindTools, with debuffs to the left of that, buffs to the right. Above it is a hidden DataBroker bar with Barzooka that only shows on mouseover. That's where I stash some random info like CPU usage, gold/currency, bugsack, WIM messages, or addon quick access that would normally be attached to the minimap.
In the middle of the screen, you have the WeakAura timers on the left, on the right are the Boss/Tank bars setup via Elv (though, do I ever wish I could use the databar there like I can on other unitframes), and in the middle, below the character, is Hekili (RIP). The nameplates you see in the show are done via Plater.
At the bottom, you have the usual suspects, though I've replaced the Elv chat with Chattanator. Actionbars and Unitframes are done via Elv, and the Minimap in the middle is SexyMap. All of that is set up on top transparent bar via ChocolateBar (I'd use Elv's bar, but it doesn't seem to have any adjustment for it's transparency level, and the default is too dark for my taste). Finally, there's a custom skinned version of Details sitting next to chat that I adore.
The raid frames are on the far right and adjust dynamically to fill up the space as best as possible using the options in Elv. This doesn't work well with healers, but I'm bad at healing and don't play them (tank main), so I'm not overly concerned. In a 5-man, the space fills up and takes advantage of the 3D character models. After that, the bars scale for like you see here in this shot in LFR.
Lots of other addons being hidden here like CursorTrail, Dialog UI, Kaliel's Tracker, OPie, Plumber, Baganator, WIM, etc.
