XT12 ethernet port 3 yellow?

Will a 100mb device always cripple the speed of the whole nod?

If you don't have a switch to buffer it to the higher speed network it would.

no other devices on other lan ports or wifi are not impacted

I can probably get around this then. What type of switch should I look for? A managed switch?

I would recommend a managed switch. Which there is an array of them. But get one that has two uplink ports. I recommend getting one with SPF+ ports so if you ever upgrade in speed, all you would have to do is change modules and don't have to replace the switch.

You don't need any switches. Most likely bug in firmware.

And definitely don't put a managed switch between Main and Nodes in AiMesh.

One would think that would be the case, however, It mainly causes congestion. Since the router is not a network segmenting type, but a spanning switch, all ports will see the 100M packets which will switch the mode of the Ethernet interface into promiscuous mode. When this happens, it will have to look at all packets sent on the network, not just packets sent to it. The end result is more load on the CPU and speed is still limited by the slower part of your connection path even though it is connected on a different router port.
