Multiple RGB outputs
Sweet. Then pretty much any arduino or other microcontroller would take care of what you need. The strips only take one output pin plus power and ground so just about everything will work for driving them. They act like a long shift register so the single pin is all that's needed to load the full strip with whatever patterns you want regardless of the length. You just have to tell it how many LEDs there are in total is all. Check out the FastLED library. You can learn more about it there and/or install the library in the IDE by pressing "ctrl shift I" for windows or "command shift I" for mac and search for it in the upper search area and install it right there. It comes with working examples too so all you would have to do is install the library, load one of the new example sketches that came with it, and probably edit the example to change the NUM_LEDS count to match what you're working with.

Hi everyone, which cheap & available controller is a good choice at the moment? Requirements: 200+ MHz & FastLED hardware SPI support. I've an ESP32 V4 in mind. Or maybe an ESP32-S3FN8. Any experiences, comments or suggestions? What is widely used currently?
I highly recommend the Teensy 4.x with the OctoWS2811 driver. This driver provides 8 channels of parallel output using DMA data transfers to offload the CPU. I think that meets your criterion for "hardware SPI". It doesn't seem like the T4 is overkill for what you're doing, especially if you're using floating point math. The T4 is blazing fast, and I've heard mixed reviews of ESP32 FP performance.

How would I recreate the strip lights from the top?
They are actually quite easy if you have some cash. Check out NeoPixel at Adafruit, they have a detailed guide on how you can control strip lights. NeoPixels are great but a tad expensive, you can find less expensive strips on discount resellers, search for “RGB Addressable LED Strip”. Some offer a control module but you will be limited the the built-in color patterns and speeds. If you can solder and program an Arduino you can modify example scripts to do a lot of things, even create digital signage and video walls.

New to this. Suggestions for controlling 2,016 WS285 LEDs?
Assuming you're going to use the OctoWS2811 library to drive the LEDs, the maximum possible frame rate for 2 channels of 1,008 LEDs should be:

Best µcontroller to handle 600 LEDs, fastest as possible
However, if you have all 600 LEDs in a single strip, and the strip is WS2812, then you're limited by the internal refresh rate of the LEDs, which brings you to about 55hz. Which is ok, but if you spend much time in-between refreshs, maybe it's not fast enough. Certainly not for persistence-of-vision. If you're happy to break your strip into several sub-strips that get their own data line, you can speed up the refresh rate a lot. If you're using a Teensy 4, you can use this library for example, which allows you to efficiently drive many LED strips at once: https://www.pjrc.com/teensy/td_libs_OctoWS2811.html

Thought about FastLED and RGBW
I've used RGBW for a number of projects involving non-addressable LED strips and spot lights. I haven't yet needed RGBW for a project requiring addressable strips, but it's in my tech roadmap. I no longer use FastLED, and I've written my own HSV/HSI-to-RGB/RGBW color conversion library. I use the OctoWS2811 library (not the adapter board) for DMA-based serial data output to addressable LED strips. It appears that this library supports RGBW strips, but I haven't tried it yet (others are doing the same). See the last few paragraphs of this article for more details.

FastLED 3.5.0 was released
But the OctoWS2811 Library can only use 8 Pins, at least on the page is only for a Teensy 4.0 and 4.1 the hint, that any group of pins is possible.
