Microsoft posted an article saying that Internet Explorer users will be able to continue using Adobe Flash Player until Summer of 2021 by opting out of applying a special Windows update designed to remove Adobe Flash Player, e.g. for mission-critical exception cases in enterprises. However, I see that Adobe has documented that they will start blocking Adobe Flash content starting Jan 12, 2021. Will that block it also for IE11 exception cases where Flash is not removed by Windows Update?
Yes, Flash content will be blocked in all browsers starting January 12th. You would need to configure an AllowList to keep using it. See the 'Enterprise Enablement' section of the administration guide. Note that the AllowList only works as long as the browser supports Flash (so for IE11 as long as you don't install that update).

As the last poster noted, Flash Player will stop loading content from the open web after Jan 12, 2021. More importantly, the last monthly update to Flash Player has already shipped.
Since Flash Player's job is primarily to process untrusted content, we continuously and proactively update it to stay ahead of the latest academic research and intelligence from the field. That work has stopped, and we strongly recommend that you uninstall.
For enterprise organizations that need to keep important legacy applications working, you have a couple options, outlined here:
For consumers, we recommend that you simply uninstall and find alternative content and games.

Microsoft Update for Removal of Flash Player
Our workflow requires that during our QA process a tester compares the legacy Flash content with the new Canvas content. We produced content for clients that has been long in use on their systems. Some of it dates back to 2004. Although we've advised them of Flash EOL, there has been a fairly flat response, mostly due to cost to convert (and we are very competitive).
The packaged browser is great, but cost prohibitive. Even with our largest outstanding clients, we couldn't justify the expense of enterprise software. We would be unable to pass it on and the need is limited and temporary. Ideally, we'd be able to launch a desktop application (such as Flash Projector) and interact with the locally loaded swfs. We don't need the browser functionality. Just the ability to launch local swfs to QA interactions and animation.
If Projector was going to continue to operate, we could build a bench player that allowed us to click through the functionality of the each swf. How can we address this issue?
