Chris,
You're right that our rule books for UEB Math/Science do not show any examples like the multiplication problems you shared (i.e., spatial multiplication problems whose factors include decimals). Following print alignment within the problem is likely your best approach. That is, right-align the factors, and do not align by place value in these multiplication problems.
One potential transcription of your example problems is attached (as an image and in a .brf).
