Your primary need dictates the choice. If you require wireless operation for a clean desk or multi-device use, and value the novelty of a smart screen, the AULA F75 Max is the logical pick.

AULA F75 Max vs Keychron C3 Pro: your questions

Yes, the Keychron C3 Pro listing includes Mac/Win support. The vendor description specifically mentions a shortcut (FN + Caps Lock) to switch between Windows and Mac keyboard layouts.
The Keychron C3 Pro offers deeper software customization. It supports the open-source QMK and VIA firmware, allowing for extensive key remapping and macro creation through a web app. The AULA F75 Max uses proprietary software for remapping and screen customization.

The AULA F75 Max vendor description mentions layered foams including an IXPE pad and PET pad for a thocky sound. The Keychron C3 Pro listing includes 3.5mm thick EVA acoustic foam, IXPE film, EPDM foam, and a silicone pad.
This depends on keycap compatibility. The AULA F75 Max uses south-facing RGB LEDs, which avoid interference with Cherry-profile keycaps. The Keychron C3 Pro uses north-facing RGB LEDs, which its vendor says make shine-through keycap legends brighter.

No, the Keychron C3 Pro does not have a dedicated volume knob or a TFT screen. Media controls would need to be accessed through function key layers.
The AULA F75 Max is more portable due to its wireless capability, built-in battery, and slightly more compact 75% layout. The Keychron C3 Pro is a wired-only TKL (80%) keyboard, making it less convenient for use away from a desk.
