RE: one-sided concrete wall
Why are you doing this?
Is the CMU wall failing somehow?
Is this for a new building next to a lot line?
What is the foundation soil like?
Is the CMU wall part of an existing building?

I suppose another option would be to brace the CMU to resist the loads applied by a one sided concrete form, but the A-frames needed for the concrete side and the bracing needed for the CMU side would be challenging and expensive. Though there are likely some hungry material suppliers these days that might be willing to undersut there prices for years to come by going absurdly cheap.

Not that I do it much myself, but I think the most common way is, in Step 3 of your post, click on the link to ENGINEERING.com, and upload your file there.

I have used it for 20'+ wall heights in multiple risks.
If you comment on flammability is related to the stay in place form - "Stayform" is a product name referring to an expanded steel mesh product. When combined with sacrificial reinforcing steel, it becomes the stay-in-place form on the the backside or blindside of a wall system.
When approving susch a form system, consideration should be given to the environment in which it is placed. The sacrificial rebar and the form ties secured to them will likely be exposed to the elements on the backside of the wall. In an especially agressive environment, this steel could be a path to the interior wall reinforcement.
An internet search should get you info on Stayform or similar material. An experienced contractor may be harder to find, but it is not an overwhelming challenge to work with, so long as appropriate materials and concrete pour rates are used.
Keep posting questions and I hope it helps.
