I recently switched to "invisible" fiber after having used various generations of MoCA/G.hn/Powerline ethernet over the years. The best part is that you can get such cabling down to 0.6mm thin (akin to fishing line) and get it pre-terminated, meaning you don't have to drill holes anywhere as it can easily fit through doorways and supports very tight bend radii without breaking (exceeding G.657.B3). Also, pairing it with bidirectional transceivers means you only need to run one cable to each endpoint.
