Building an Array of "nop" write commands
adafruit/Adafruit_NeoPixel has assembly code for AVR. Plus ESP and Rpi which are a lot easier to read. And the protocol does look like inverted WS2812; it should be possible, although tedious, to modify the library to invert the pin.

What is causing a delay in my loop?
I looked at the neopixel github and I couldn't find any functions that took floats as arguments, so I think you can get away without using floats because they're reinterpreted as ints and truncated anyway, but if what you have works then don't bother.

RGB/RGBW mix and match help!
I'm not sure if that is the same thing. Back when I used it I got it from Adafruit which links to this Github.

NeoPixels on the Arduino Nano RP2040
The most important question first, the Adafruit NeoPixel Library does support the RP2040 since version 1.10.2. So make sure you are using the right version. To install the library please follow the steps explained here: Adafruit NeoPixel Installation.

Neopixels: ultra-low RAM
The Adafruit Neopixel library is great, but uses 3 bytes of RAM per pixel....in my application that's nearly 3kB (for the pixels alone!), which rules out the M328/Uno, and basically all of the 8-bit chips. I have a prototype running well using Adafruit's Neopixel library on a Mega 2560, but those are hard to source in the current market. And it's overkill for my use case.

Is it possible to program a 5mm neopixel LED in a way where one switch turns it on, and then the activation of another switch changes the color?
Using something like the Adafruit NeoPixel library there are commands to set intensity and to set color: setBrightness() setPixelColor()
What are some alternatives?
