Wanting a recent Orbi router Mesh, satellite 4 port for large home thx

Hi, I like this Netgear mesh rbk40 product but prefer a more updated model than 2017. Is there a Netgear product without having to buy more than two products? My house is large, looking at Netgear, not looking at 3 lots of Netgear products, 2 products is okay, tri band, ?Satellite (for Nbn), Ax? mesh, 4 port, boosted wifi, no wifi dropouts, same network and passwords and works seeming less without changing networks as I go through the house, I’d like it to work with google home. What do you recommend please? Or is this the only product? I'm in Australia.   Any help is appreciated.  Thank you for your time
