I agree with @rcm1203. Replace all your Ethernet with cat8 cables from Amazon. They’re all triple shielded and will definitely improve things. And they’re good for 10G. I changed everything in my house to Phizli. Cost is only pennies more than your average cat6.
I have a 4 server 2 desktop plus Orbi 960 system running up to a full 10G across a Dell 8024F switch. Cleaned up all my streaming stuttering issues too (Sonos) .
Also don’t go with your isp routers. They’re useless and can provide you a decent firewall and high speed at the same time.
I’m possible way above most of what people are using in that I’ve got a 2.5Gb symmetrical fios feed from Ziply (I’m in Washington), use a SonicWall TZ470 for my router/firewall, and use various multi-mode (1/2.5/5/10) and single mode (1G) SFP+ GPICs as the switch is a 24-port SFP+ switch (I use Cisco, SonicWall, Finisar)
