Devices needed to take advantage of 1200Mbps plan

I'm wondering if there are any devices that aren't the xfinity modem/router that takes advantage of this plan? I found one person that explained the setup with a 3.1 modem and a Dream Machine Pro, but not necessarily looking to go that route if there is other options available. The person that wrote that article was able to get 1444Mbps so pretty big jump from standard gigabit. Is this the only option or are there cheaper alternatives?

Approved retail devices for use with 1.2 Gbps Internet are listed at https://www.xfinity.com/support/devices/.

Sorry that's not really what I'm asking. I know what modems offer multigig. I'm looking for devices to route it from there. My issue is there only being 1 2.5gps port on basically every retail device I'm ever seen so there isn't any way to get these speeds from the modem/router to the devices. Hopefully that makes more sense.

Do I just need one of these modems and then a switch with multiple 2.5gbe ports?

AIUI hanging a switch off a modem port will only make one of the switch ports active, unless you are able to subscribe to "Additional IP Addresses".

You might try reading some of @jlavaseur's posts. He claims to get 1400 Gbps (ex: https://forums.xfinity.com/conversations/your-home-network/wan-bonding-to-achieve-speeds-higher-than-940-mbps/6063b16ea12cff7d105aab60?commentId=6088ab13048e670ca85cfc93) by feeding the 2 outputs of a LAG-capable modem or even 2 of the ports of a Comcast gateway into an ASUS router that has dual WAN support. 

Note that hanging a router off a gateway that is not in bridge mode creates a "double NAT" condition that has some drawbacks. See https://www.google.com/search?q="double+NAT".

@BruceW with this setup the 2.5gbe port would still be available but would only be able to have one device (pc) connected running the higher speed, right? Seems like the modems and routers just need to catch up with the increase in speeds from Internet providers.
