I've made a simple drawing to better illustrate my situation.

To begin with, I thought of digging out my old TIME router and place it in the storage room, then connect it to the switch, where it'll be connected to the LAN port in both the living room and master bedroom, and use the 2 new mesh routers as AP, but even with that set up, I'm still unable to make the most out of my 600 Mbps as I lose 200 Mbps just by being 3 meters away from the router.
As I don't believe that is normal, this leads me to the conclusion that the Wi-Fi capability of this router is trash, hence my rationale of getting a cheap modern Chinese router with strong Wi-Fi capability to use as an AP, or at least strong enough to cover 700 ish sqft. I don't really need the router capability if it's not compatible with our local configuration. But if it does, 1 less device = save more electricity!
If you have LAN port built into your home, then you can consider using AP mode to maximize your signal and speed throughput.
Places where you don't really need full speed, you can get a used or new WiFi5 gen. But I suggest that if possible, get all the same model for better setup and fine tuning later on.
In my case for example, running two deco x50 as a main and wireless node, while my 1st floor, I used back what was provided by my ISP and can be paired to my main X50 nodes effortlessly and is directly wired to the main node on ground floor. The fast roaming works perfectly as of now, almost 1 month no issues or weird bugs anymore. Infact, is even better at coverage if compared to a X50 I used at the same spot for the same floor.
You can always look for Deco that supports ECO mode, but this only on a certain model with a certain firmware. Like the Deco X50 i'm using I can schedule the Wifi to turn off automatically at a certain time and leave only 2.4Ghz to be turned on.
ASUS has that function too if I'm not wrong.
There is no balance to it, if you want full coverage you got to install more APs or mesh around the house and that would definitely consume a little bit more of electricity at the end of the month.
About the router provided by your ISP, maybe the signal strength coverage is set to low or standard? I'm not sure, but you got to login into it and check the settings, sometimes routers comes as default setting. hence why I said needs fine tuning earlier.
