At 5,000 square feet, stop shopping for coverage and start thinking about backhaul. You will need three or four nodes, at least one of them two hops from the base, and on a wireless backhaul that node will be running on a quarter of your speed. The answer is either a quad-band system with a dedicated radio for the nodes, or — much better and much cheaper — Ethernet.
Why this size is different
Every hop on a wireless mesh costs throughput. On dual-band it is roughly half per hop; on tri-band with a dedicated band it is much less, but it is not nothing, and a node relaying through another node pays twice. Small houses never reach a second hop. A 5,000 square foot house reaches it routinely.
There is also an airtime problem. Four nodes plus thirty devices in one building means a lot of radios politely waiting for each other. Adding a fifth node to fix a weak corner can make the whole network slower. This is the size at which more hardware genuinely stops helping.
Try this first
At this size, wiring one or two nodes changes the entire outcome
A single Ethernet run to the node furthest from the base converts the worst link in the house into the best one, and it removes the second hop for everything beyond it. If a cable is impossible, check for coax: MoCA over existing coaxial outlets gives you a shielded gigabit-class path for the price of two adapters, and a house of this size almost always has coax in several rooms.
How to plan a house this size
Find where the modem is and accept it. That is node one, and it is often in a corner. Plan around it rather than fighting it.
Identify the two or three places a node must go — the middle of each floor, and any wing that is past a solid wall.
For each of those, ask: can I get a wire here? Ethernet first, coax second, powerline third.
Buy a system whose nodes have real Ethernet ports so the wired options stay open. A system with one port per node forecloses them.
Only then choose between quad-band and tri-band. If every node will be wired, tri-band is already more than you need and the quad-band premium is wasted.

How we picked
We do not run a test lab and we are not going to pretend otherwise. Every ranking here is built from three things: the manufacturer's published specifications, measurements taken by independent outlets that do have labs, and the structural reasoning on this site about what a given house actually needs. Where a number appears, it is attributed and linked in the Sources section. Where we have no basis for a claim, we leave it out instead of filling the gap.
The scoring rubric is visible on every pick so you can disagree with the weighting rather than just the conclusion. Our full methodology spells out what we will and will not assert.

Common questions
How many mesh nodes for 5,000 square feet?+−
Three or four, depending on shape, floors and wall material. More than four rarely helps and can hurt: each node is another radio competing for airtime. If you need more than four, the real answer is wired access points rather than more mesh nodes.
Is quad-band mesh worth it?+−
Only in a large house with no wired backhaul. The fourth radio exists to carry node-to-node traffic without competing with your devices, which matters when nodes are two hops apart. If you can wire the backhaul, the quad-band premium buys you nothing.
Can I mix wired and wireless mesh nodes?+−
Yes, and in a large house you almost certainly should. Most mesh systems detect a wired uplink automatically and prefer it. Wire the nodes you can reach and let the rest connect wirelessly — a system with several Ethernet ports per unit makes this much easier.
