4-wire LED strips? You mean the Common Cathode Anode RGBs like these guys? https://learn.adafruit.com/rgb-led-strips/wiring
Unless you have a chipset for whatever 4-wire LED you're thinking, I don't think those are addressable LEDs in any way.

Oh, APA102 is definitely FastLED capable.
Not sure about SK9822.
Oh, wiki says yes.

Yes, but specifically the parallel stuff
To control multiple strips in parallel rather than serial.

Oh, that. I highly doubt it. The clock speed needed to run those things are pretty high already, so I'd be surprised if most microcontrollers could handle multiple strips in parallel.
The parallel output functionality is typically used to try to get faster response on the slower WS2812 chipset, but even 8x speed on WS2812 is nowhere close to that of the APA102.

Two people were working on it, and there numerous github forks fro ESP32 doing parallel strips, mostly from 2018, but one by a person named Sam Guyer who has made other FastLED commits.

Well, I've never touched those before, so not familiar with that. What type of application are you working on that requires parallel APA102s?
low bison
I doubt it would need it, only ~92 LEDs, but it's 8 edges of a cube and parallel strips would make pattern composition easier for the human brain. 🙂

Well it looks like there ARE experimental builds for parallel APA102... https://github.com/hpwit/I2SAPA102
