I have had issues with GSX, but different to you. The integrated GSX in the efb, didn't give me the option to confirm good engine start! No idea why. It did work if I turn GSX integration off in the efb and use the top GSX menu within the FS2024 sim. Another thing to bare in mind. There have been several reports that using a Tug that lifts nose wheel rather than a towbar, receives a nose gear oversteer warning message. You can force GSX to use a towbar from the GSX editor.

I have the WINWING FCU and Left EFIS. I have selected the option in simulation to sync CPT/FO but it seems that the FO side is the controlling pressure setting! Other than that, the FCU and aircraft run very well in 2024. Need GSX to update as there are a few issues with pushbacks. Eg select a towbar pushback truck to avoid oversteer message.

Apparently the beacon light will automatically script the chocks to be removed and ground power disconnected. Make sure the APU is up and running before preparing for pushback (gsx). And turning on the beacon. Maybe strobes are the same.

I had same issues. The BCN I believe is a bug. The aircraft goes dark as the BCN seems to disconnect ground power. Then once the APU is up and running, power is restored. As for the steering. Check the options in the efb. Set use rudder as tiller to ON, by default mine was set to off.

Do you use GSX? I have had issues where GSX only works with a towbar pushback tug. If you have wheel lift tug, it often results in a broken nose gear!

In FS2024, The GSX loading for fuel loads fully according to simbrief value.
