Building a Music Production/Mixing Machine (Specific Hardware Questions)

Hello!

I am currently planning to build my second hackintosh, with my first being completed over ~7 years ago. This time, I am planning to make a pretty maxed out macOS Catalina machine for Music Production & Mixing (Ableton & Pro Tools).

Here is the list of the parts I plan to use: https://pcpartpicker.com/list/nwhWRT

Before I pull the trigger and begin this journey once again I want to make sure a few things...

1. I currently use the Apollo Twin Duo & Apollo Octo Satellite as my audio interface and DSP card, which utilizes a thunderbolt 2 and thunderbolt 3 connection respectively. With the Gigabyte Titan Ridge PCIe thunderbolt card, I should have OOB support after switching some settings in the BIOS correct? Some of the past posts on this sub-reddit are a bit unclear on whether TB2 & TB3 were successful, especially with the Apollo IMO.

2. Moreover, I want to use the LG Ultrafine 4K Display found in the Apple Store as my main monitor. Will the Titan Ridge card & Intel 630 UHD be sufficient to use this display? I don't plan on buying a graphics card unless mandatory to utilize this display.

3. Just to double check, the fenvi FV-T919 WIFI card should give native support for HandOff/Airdrop, and all other Bluetooth/WIFI related Apple features correct?

4. Finally, I am a bit confused by two of the PCPartPicker Warnings on the M.2 drive. Am I allowed to utilize 2 M.2 slots at once? The warnings being:

   1. The motherboard M.2 slot #1 requires an Intel Rocket Lake-based CPU. When an Intel Rocket Lake-based CPU is not used, the M.2 slot is disabled.
   2. The motherboard M.2 slot #2 shares bandwidth with a SATA 6.0 Gb/s port. When the M.2 slot is populated, one SATA 6.0 Gb/s port is disabled.

Any help is much obliged, thank you so much!
