Thoughts on Netgear AX1800 WiFi Router (R6700AX) for main router and AP?

I have 100(down)/10(up) spectrum service with a spectrum rental router set up in basement. I work from home and have a gaming PC in the basement so having the router in the basement has worked well Except for the far end of my house, the WiFi gets a little weaker/slower. This is where my main TV/Xbox is.

I’d like to replace the spectrum rental router and run a Cat6 Ethernet cable to the far side of my house and set up either a router in AP mode or a dedicated AP and switch

I’d like to hardwire my TV and Xbox so I’m thinking just getting a router with 4 Ethernet ports in putting that router in AP mode to improve WiFi.

I’m thinking the I could get two $90 AX1800 WiFi Router (R6700AX) and one would be my main router and the other would be act as an AP.

I would appreciate any thoughts on:

1. Is there any reason to get an AP and switch versus just getting a router in AP mode?

2. anyone have experience with the Netgear AX1800 WiFi Router (R6700AX) or have other recommendations for a similar cost ($180 for both)
