Which of these is most likely to contain (the most) comments on creation, creation theology and/or environmental stewardship? I can get these once per year for free to get a course as long as I use them within 6 months.
Here are a couple more to consider (sorry, I have no direct answer to your original question)

If I understand correctly, you are looking to use your Faithlife Connect free course access. In that case just go for what you thing will give you the best overall coverage. Both theology courses will be covering far more than just creation. But that also means that they will most likely be devoting far less coverage on that one topic.
Just my two cents.
I have these courses, so I made a very quick review of them to provide this:I don't think that any of these courses offer much of what you are specifically asking.NT305 New Testament Theology Moo has almost nothing that I see on creation--he refers to it briefly in a few paragraphs. He touches very lightly in a couple paragraphs on environmental stewardship.
OT 300 Bruce K. Waltke touches lightly on evolution in a few brief paragraphs and seems to lean toward "Evolutionary creationism." He stands against Darwinian evolution but minimizes importance of the matter. Not much else. I see nothing on stewardship.
OT312 Deut--I don't see that it touches on these topics much if at all. I might have missed it. OT 312 seems to recognize and assume creation in the garden, but not a lot more.Keep in mind that most of the content of courses such as these might seem like a lightly brushed overview--depending on your background. But they offer references to many other resources so you can dig for more on your own.
