MacBook Air M5 (16/512) vs. Buying Asus Zenbook 14 OLED UM3406KA (32/1TB) for post graduate study

As mentioned in the title, I am looking for a new laptop and am currently stuck between two options. My work generally includes:

• Budget: ~1000 USD
• MATLAB/Simulink
• CAD work (AutoCAD)
• 3D modeling (Fusion 360)
• Light photo and video editing
• No gaming

I have heard that the MacBook offers superior battery life and does not require being plugged in to utilize its full performance. In my country, both devices are similarly priced.

What is the difference between the display of both devices? Additionally, is the performance gap between the M5 and the M4 significant, or can I get away with the older MacBook Air model?
