Lucky you. You have Fiber.
I'm still local cable company broadband. 300+ megabits down, but only 6 megabits up. And I share it with my Wife, who is also a computer professional working form home (different companies). But it works for us.
My home is wired for Ethernet, so the wall jack next to my desk goes to the gigabit switch in the basement, which is then connected to the eero 6E mesh node that is also the router, which then plugs into the cable modem.
When I had the house wired, I put an electrical outlet into all the closets and 2 Ethernet wall ports. So the eero 6E mesh node is in the kitchen closet using one of the Ethernet wall ports to connect from the WAN port to the cable modem the basement. The 2nd Ethernet wall port connects from eero 6E LAN port to the gigabit switch in the basement. The switch then connects to the two other eero 6E mesh nodes, so I have a wired backhaul. The switch also connects to my Synology (and my 2nd Synology that backs up the first Synology), my Brother multi-function printer in the foyer closet (2nd closet Ethernet line does not connect to the switch, but rather the telephone line so I have FAX service from my printer; I had to attach an RJ-11 connector on the basement end of the Ethernet cable in order to do plug into the Telephone line), the Ethernet capable TVs, the Apple TV, an old Mac in the basement I use as a server, and a few other devices.
All other network capable devices use the WiFi.
I have about 50'ish devices on my home network, between computers (multiple for both me (about 5) and my wife (about 3); it is hard to keep track), iPhones, iPads, iPod touch (or old iPhones used as a Touch), Ring door bells, Roomba vacuums, TVs, Apple TVs, webcams, NAS servers, etc...
I'm glad I was able to answer your question. Have a nice rest of your week. Maybe it is warmer where you are than it is here (27ºF ; -3C, and everything is snow covered)
