Buy one of the new ones with MIMO technology. It's made to have different streams that are independent of each other and also has more than enough throughput. something like this
I have been very satisfied with my TP-Link AX-6600. Their firmware is not very impressive feature-wise, but now that I have OPNSense running and it's in access point mode it doesn't really matter anymore.
They would all be going from the Ethernet in the router to a switch or moca adapter to connect to the access points. Also would this router work for it?

I have a 2100 Sq ft, 2 story house with a finished basement. I purchased an Ax6600 ( https://www.amazon.com/dp/B08TGPTQ14/ref=cm_sw_r_cp_apa_glt_fabc_Y02QREGT08CS3KH279HN?_encoding=UTF8&psc=1) and mounted it near the ceiling on the first floor. The coverage is great. I have not found any dead zones and it does a fantastic job of seemlessly switching between 2.4 ghz and 5 ghz.
That's a little bit more complex subject... You will need to use a DUAL WAN router.
If you're not in IT - which I assume you're not since you're asking this question -, your best bet is to find something that will do that for you in a easier way to setup, like something like this: https://www.amazon.com/TP-Link-Archer-AX90-Wireless-High-Speed/dp/B08TGPTQ14/ref=sr_1_7_sspa?keywords=dual%2Bwan%2Brouter&qid=1650057608&sr=8-7-spons&spLa=ZW5jcnlwdGVkUXVhbGlmaWVyPUEyVUJUN0ZMUlVaN1BDJmVuY3J5cHRlZElkPUEwNTE5Mzc3WUtSS0ZXRjUzSUQ4JmVuY3J5cHRlZEFkSWQ9QTAwMjgzODAzQURWQjhJNUZITUcwJndpZGdldE5hbWU9c3BfbXRmJmFjdGlvbj1jbGlja1JlZGlyZWN0JmRvTm90TG9nQ2xpY2s9dHJ1ZQ&th=1
Now, I don't have a dual WAN router, so I can't be of much help, but usually the TP-Link (or any other mainstream "BestBuy" brand should be pretty easy to setup).
Obviously there are other types of routers that will do that in a more robust way, but again, that's for people who work in the field.
