Does it have hardware PPPoE offloading? Because it's a huge issue for those of us stuck with old-school telecoms for our fibre connections. Doing PPPoE at gigabit speeds needs something that can handle it.
Have you looked at the BPI-R4? It's a pricier option than the OpenWRT One, but it has excellent hw acceleration for networking tasks. I am 90% sure I recall someone reporting using it for a 2.5Gbps PPPoE connection and it handled it. It's also supported by the OpenMPTCProuter project if you need network aggregation support.
Yes. Mediatek SoCs have hardware acceleration support for that.
