Deco seems the STW system of choice. I’ll throw in my suggestion of ASUS. I have a pair of ASUS Zen devices and an old AC-86. There’s some interoperability of ASUS routers in the MESH setup so you can mix and match to a degree.
Important thing will be whether you have hardwired backbone or need to have wireless backbone. This is how the individual MESH access points share the connection.
If you can connect your access points with cat5e, or better, cabling that’ll be best. You only need a dual band MESH system for this.
If you need a wireless backbone then get a 3 band MESH system that will let you devote one band to the backbone. This leaves the others for your devices.
TP-link do deco tri-band systems. ASUS do tri-band systems too.
