Have been using Linux since Slackware in the early 90s, both for work and at home - been through a lot of distros since then.
Currently use Debian on my servers and VMs, and CachyOS (with KDE Plasma) on my main desktop. I like the bleeding edge of Arch for my desktop, and find CachyOS to be a very sensible plug and play way to get into Arch (I tried to run Arch before, and also EndeavourOS, although that was a while back and not the smoothest experience for me - things might be more mature now, but CachyOS was the one that finally reached the point for me that allowed a full switch from Windows on the desktop to Linux)
Most of my servers run virtualized on Proxmox, which itself is Debian based though. I also run pfSense as my firewall/router which is FreeBSD based.
MoCA is honestly really great. I’ve been running 4 MoCA nodes (2.0 and 2.5) in my house for 10 years now, over pretty shitty RG58 cabling and a bunch of splitters, quite long runs too, along with 1 gig DOCSIS 3.1 modem sharing the same cabling, and it has been absolutely bulletproof and reliable (especially compared to the powerline ethernet I was using before, which was absolutely terrible). Plenty of bandwidth for full duplex 1 gig - really the only downside compared to 1 gig ethernet is a few extra ms of latency.
Running ethernet cables everywhere would be very expensive in my situation, and while I considered it a few times to get more bandwidth between my main computer and the NAS which sits in my homelab in the basement, I still find it hard to justify the cost. If I were to pull the trigger now, I think I would go with fiber (or maybe both) - but I would have to replace so much stuff to get up to 10 gigs, all my homelab equipment is 1 gig only, server nics, NAS nics, switches, etc… it would not be cheap, beyond even just the cost of running the cables. So I am just sitting back and waiting to see how the technology evolves for now.
