I looked it up, and the Filogic 880 was the first search.
ARM Cortex A-73 CPU - should be doable
USXGMII 10G Ethernet - Would require the vendor to write drivers, or provide open source drivers that could be modified to work with FreeBSD. Being an AMD product, there may exist open source specifications or drivers that could be ported
Mediatek NPU for QoS, etc - would need special instructions written for FreeBSD to take advantage of, either by Mediatek, or if they have open sourced the specifications, someone with the knowledge and skill to write that into the FreeBSD code.
Wi-Fi 7 connectivity - Looks like some work is being done to support the Mediatek Wi-Fi chip, see:

Even if all the specifications for the hardware were open to develop on, making an OS work with specific hardware is not trivial. As is the case with most hardware appliances, there would almost certainly need to be a commercial incentive to put in the required work to use this hardware with a FreeBSD-based router OS. Someone like Juniper for their proprietary OS, or if NetGate decided they wanted to offer pfSense boxes with this hardware.
