Thank you, John, for trying to help me with this. Unfortunately, your tips wouldn't work with my situation, which I'll clarify here:
The end goal is to have a "sticky" HTML block which is hidden on the front page, but visible in every course, but only to TEACHERS and not students. This could be either with editing turned off or only when it's on. In the past (Pre-Moodle 3.9), I was able to successfully accomplish this ONLY with editing turned ON and I just accepted that. If I could do it with editing turned OFF, that would be a bonus. Too help understand the use for this, I'm including an image of one of the sticky HTML blocks we use:

Previously (Moodle 3.6), I was able to create this scenario following these instructions
Making a block sticky throughout the whole site: https://docs.moodle.org/39/en/Block_settings#Making_a_block_sticky_throughout_the_whole_site
Then, still from the frontpage, I would change the Permissions the moodle/block:view to ALLOW Teachers. I wouldn't even need to Prohibit students, although I've been trying that while struggling through this.
Note: Then (3.6) and now (3.9), our defaultfrontpageroleid was the role FRONTPAGE (based on what I'd read here: https://docs.moodle.org/32/en/Front_page_settings#Default_front_page_role )
While trying various permissions to get this to work in 3.9, what surprises me the most is that Prohibit seems to do nothing, at all, when I set it for moodle/block:view.
