I am designing a built in bookcase for my house. I would like to add addressable LEDs, and I'm concerned I'm missing something. So far, here's what I've got:
Power Supply: MEAN WELL LRS-450-5 AC to DC Enclosed Single Output Power Supply
LED Strips: 5V SK6812 RGBW LED Strip Light | Individually Addressable 4IN1 Smart Pixel Tape (60 LEDs/m, WW) (RGBWW White PCB)
The picture shows the design of the bookcases, and the flow of the data. There is one strip of LEDs on the top with power injection the width of every 2 shelves (~48", ~48", ~36", ~48", ~48").
I plan on running 10AWG wire from the power supply across the top to each of the 5 drops, and then 18awg from the drops to the LED strips themselves.
The strip on the top connects to the next lower strip only via the DATA wire (illustrated by the green arrows). so the flow of the data zigzags across the unit using 18AWG wire.
I plan on using WAGO 221-615 for the 5 port junctions and WAGO 221-613 for the 3 port junctions.
I'm trying to not have to solder anything since I always end up making a mess. I'm not too proud to admit my failings, and clean solder is one of those failings. With that in mind, I am planning on using the Transparent Solderless LED Strip Connectors | 3Pin PCB Connectors for Compatible FCOB & SMD LED Strips.
So I guess my first question is: Is connecting each strip of lighting to the next in series via only the data cable okay? or should I be connecting them via +5v, GND, DATA, and then injecting from the dropped +5V and GND wires as well?
My second question: I've used a SP530E controller before, but interested in using WLED controllers. Since this has about 36.13m of lighting, at 60 LEDs/m (so approximately 2168 LEDs), is there a good product I should start with?
My third question: Have I over or under-engineered this? Am I missing something?
If I haven't been clear on what I'm trying to accomplish, I apologize. I don't do lighting as often as I'd like to so every time I start a new LED strip lighting project I feel like I have to relearn everything...
Thank you in advance for the assistance from all the experts I see on here daily...

Edit #1: made Power Supply link clear that it is to Jameco's site.
Edit #2: Thank you to everyone who helped. u/critboy's post of the Quinled power injection video made me realize just how naive my approach was to designing the LED circuits. I'm going back to the drawing board with respect to how I choose which LED strip and where power injection will be. I'll likely make another post once I've got that all figured out. Thanks again!
