Thank you, all, for your help in rooting out this information.
So with your help, copious surfing, and Wikipedia:
The uber-fast 5G FR2 or mmWave is not available yet anywhere in Canada. Only in the US. As of today, Rogers is the only 5G player in Ottawa (where I am).
The Apple iPhone 12 that IS capable of the faster 5G FR2 is only sold in the US. You can physically tell by an extra door outline on the right side of the US iPhone 12 that isn't on any iPhone 12 sold in Canada. If you look at the opening animation at Apple.com vs the same on Apple.ca you can clearly see it.
The vendor makes the phone to the specs of the carrier for their networks, for their country.
For me, the Samsung Note 20 Ultra sold by Rogers, is hard wired for the sub6 5G FR1 bands n41,n66,n71 only.
Thanks. This is very useful information. It still does not answer my question, though.
In a nutshell, the question is why is the current iPhone 12 series not compatible with the new Rogers standalone networks? This is not about FR2 or the 3500 Mhz band, for which Rogers does not have licenses yet. The government auction for 3500 MHz is to be held in 2021. So Rogers cannot install anything yet. Currently Rogers has n41 and n71, whereas Bell/Telus have n66.
My understanding is that a non-standalone network also uses 4G infrastructure jointly with 5G, whereas a standalone network uses solely 5G infrastructure. But I suppose they should use the same frequency bands, and only the backbone network may be configured differently.
For information, the Canada version for the iPhone 12 Pro Max (A2410) is compatible with 5G NR bands n1, n2, n3, n5, n7, n8, n12, n20, n25, n28, n38, n40, n41, n66, n71, n77, n78, and n79. It is not compatible with 5G NR mmWave bands n260 and n261. For the time being, the latter two bands are available in the US only.

Rogers doesn't provide N38 according to its own list of 5G bands: https://www.rogers.com/customer/support/article/unlocked-devices
I chatted with a Rogers tech rep about this and I asked why N38 is listed on all media sources (i.e. Rogers Wiki, Kimovil, etc.) except the Rogers website and which list of 5G bands is the true and latest list:
https://en.wikipedia.org/wiki/Rogers_Wireless lists N38
Anyways, the Rogers tech rep was was pretty rude and only gave me one worded answers, like "no" and just linked me to the Rogers link that I initially sent her.
Not sure what to make of it and nobody has given me a straight answer yet so I'm stalled on buying a new 5G capable phone. Is it N41, N66, N71 along with N38 or is it really just the first three?
I cannot find anything on the first link you posted regarding 5G NR bands being used (they might have updated the page since to remove that info). That's unfortunate.
That said, I checked a Canadian cell tower map website (https://www.ertyu.org/steven_nikkel/cancellsites.html) and a lot of Rogers cell tower sites I checked on said map were showing 2,600 MHz in use, which is 5G NR band n38 according to this website: https://en.wikipedia.org/wiki/5G_NR_frequency_bands
I also found an Canadian auction result that had 2,500 MHz spectrum blocks up for auction, but Rogers withdrew from that specific auction: https://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/sf11390.html
