If you are allowed to comment on the ones you are using for the M1 that would be great. the challenge I have is after reading various articles and specs many say they will give you the world but quite often it is only in mall bites. Since i am 76 I want to buy equipment that will not only last but also be updated as needed without requiring new purchases.
There's nothing special about the wireless on the M1 compared with other modern computer devices. It is backwards-compatible with older routers, as well; even my old 802.11g router from the 1990's could probably work fine, although performance would suffer given how many computing devices are on my network, and something that old would be very insecure. Any router you could buy new in box today should be fine, and you do not absolutely have to buy the "latest and greatest."
As to buying something that can be updated without requiring new purchases... you probably know how this goes with technology

The networking space changes at a fast pace, and the wireless network even more so. You don't
have to upgrade to the "latest and greatest" in most cases. Here's something where you'll come upon some terminology, though. The most recent, big change was the development of something called Wifi 6, which was a big deal for a few reasons, most notably that they did started moving away from the old wireless protocol naming scheme (at least, consumer-facing; you probably memorized 802.11b/g, maybe 802.11a, 802.11n, and then 802.11ac... this is 802.11ax). The M1 Macs support Wifi 6, and iPhones starting with the iPhone 11 line do as well, but I'd guess many people do not have devices that can make use of it... and that's OK, because routers are still backwards-compatible with the older devices, too.
As to not requiring further purchases, there's always something else on the horizon, and the next big router development will be Wifi 6E, which is Wifi 6 but "extended" to a whole additional wavelength (6 GHz, instead of the 2.4 GHz of g/b/n and 5 GHz of a/n/ac). That, unfortunately, will require hardware upgrades. These routers are available now, but likely very expensive (I haven't looked; I barely have any devices that can support Wifi 6 as it is).
You said you're 76; may you have at least a few more router upgrades in your life 😁
