What equipment to choose for organizing a home network?

Question

network hardware

Access to the network from the provider via PPPoE, optics from MGTS is planned later.
The apartment has a cat.6 twisted pair cable, from the one planned for connection: TVs, video surveillance cameras, video recorder, game consoles, computers, MFPs, a printer, an Internet radio server, a Home Assistant server, etc.
Tell me if the Cisco SG250 L3 switch will be enough -26 for networking and division into VLANs? Is it possible to immediately bring optics from MGTS into it via SFP?
And the second question is what equipment can be used to organize a seamless WI-Fi (ac) network of 2-3 access points, preferably connected directly to the Cisco SG250-26?

Answer 1

MGTS most likely will not let you bring anything anywhere except to your equipment, which it will rent out and, accordingly, you will not have root access. And still, you will need a router to separate such a voluminous network from prying eyes :)

Answer 2

will L3 switch be enough

Yes, L3 can create and route vlans.

Is it possible to immediately bring optics from MGTS into it via SFP?

It is impossible to say without understanding what is at the other end of the wire.

And the second question is what kind of equipment can organize seamless WI-Fi (ac) with

UniFi + their soft controller

Answer 3

Will the Cisco SG250-26 L3 switch be enough for organizing a network and dividing into VLANs? Is it possible to immediately bring optics from MGTS into it via SFP?

This is a switch. Accordingly, NAT / Firewall is still required.
Accordingly, it makes no sense to put the provider's end into the switch, its normal place is inside the local network - that is, behind NAT. Although, of course, it can be perverted)
