Better WiFi/BT module?

[xalius]

You have to keep in mind that SDIO is not PCIe or USB3.0 :-)

Does anyone know what the maximum bus speed for SDIO3.0 is on the A64?

If I read this correct, the SDC1 controller supports either

DS,HS,SDR12,SDR25,SDR50,SDR104

DDR50

SDR104 has a bus clock of 150Mhz, whichs means that at 4 bit you would get theoretically 600Mbit/s raw bit rate minus the frame/protocol overhead,
so in practice probably quite a bit less?

Tyical SDIO3.0 Wifi modules have around 433Mbit https://boundarydevices.com/product/bd_sdmac_wifi/

You also need 1.8V signaling for the SDR104 mode... which is maybe possible because Port G seems to be connected to it's own DLDO/ELDO

ELDO1 is adjustable from 0.7-1.9V (Imax 400mA)
DLDO4 is adjustable from 0.7-3.3V (Imax 500mA)

Faster modules might still give a little bit more headroom for link degradation...
