I only take issue with the stipulation here that communities should “Refuse to fund last-mile solutions that aren’t primarily fiber.” This should be overridden in all cases by the second listed yet most important requirement: “Defer to local self-determination.” The only future-proof technology is conduit in which to run new wires cost effectively at will, not any one specific wire type. Singe-mode versus multi-mode fiber shouldn’t be specified either — just use whatever gets the job done!
In the first hundreds of meters (“last mile” is a monopoly-centric misnomer), Cat6a and >10GHz wireless frequencies are actually viable solutions for up to 10 gigabits per second bandwidth, which is good enough for the latest USB 3.1v2 Type-C and PCIe level data transfer. Newer open spectrum and software defined radio technologies like Mega-MIMO and phased array antennae can actually create dynamic PtP and MPtP mobile links at gigabit speeds, ahead of any proprietary 5G cell spectrum monopolists.
The specific technology is nowhere near as important as democratic local self-determination (ie. community cooperatives) winning out over remote-control monopolists (ie. Big Telco). This principle applies to all regions, both rural and urban.
