I have that Mediatek in my zBook Ultra g1a 14, also running Strix Halo. Newer Mediatek Chip under Linux always runs shit, i have to restart NetworkManager on every connect/roam to get a successful connection. No issues with public networks that doesnt use any encryption. This is on CachyOS and Ubuntu 25.04. No issue on Windows 11.
AP i tested is UniFI and Aruba.
