Recently setup a Deco XE70 pro mesh system and it is working great.  The devices only have one 2.5 Gbps port and I would like to have another 2.5 port on the main router to network to an unmanaged switch so that devices with great than gigabit bandwidth can take advantage of the 1.25 Gig internet coming in.  It appears that all Deco routers are compatible with one another.  I assume the wifi will only be wifi 6E as that is all the XE70 system will handle.  That would not be a problem.   Is there anything I am missing and/or has anyone done similar and can advise of problems experienced.
