How does a mesh of ethernet hubs or switches work for my project?

My limited understanding of how hubs/switches work is that they are nearly identical for my needs, but want to make certain before I make a purchase to start my project. I purchased a set of mesh routers, which have been awesome, but we added a PC for my daughter to do homework and I've installed PLEX to use it as a media server. In order to patch it into the center of the hub network, I can easily run ethernet down into our basement via closets along the edge (best design ever) to a central point beneath our family room TV center, from which I also plan to drop ethernet.

The problem I have is understanding how multiple ethernet hubs or switches would work. I have an ethernet switch connecting our ROKU, smart Blu Ray player, and VOIP phone together. My plan is to replace the coax wall plate with an ethernet+coax plate and run ethernet to a second switch/hub in the basement closet. I would attach one of the mesh routers to this hub so that it would manage all of the traffic. This would allow me to shift the second router closer to my wife's office (the third router is in my office on the second floor).

Can anyone please advise what I need to consider before purchasing a second hub/switch? The current switch I am using is a NETGEAR 5-Port Gigabit Ethernet 10/100/1000Mbps Switch (GS205) - https://smile.amazon.com/gp/product/B00KFD0SMC/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Can I use a second of these to bridge the two floors?

Thanks in advance

Gigabit is all switches. There are no hubs for gigabit. Always get a couple more ports than ABSOLUTELY required. Think about the 8 port rather than the 5 port.
Performance wise, gigabit switches are all the same. Don't worry about performance between brand choices. The differences are usually the quality of the power supply.
