From what I can see, yes, methane is abstractly a worse greenhouse gas. However its absorption band is within that of water vapor. Since water vapor is plentiful around the blue marble, methane doesn’t really cause any problems.

This is incorrect, it’s well established that methane is a more potent GHG. See the reply here: https://news.ycombinator.com/item?id=21485738

What’s not taken into conservation with that comment is that methane at those altitudes does not impact much because the energy is radiate back to space.

You have doubled down on a casual assertion ("methane is not a significant greenhouse gas") because you don't understand radiative transfer in the upper atmosphere. It's OK, radiative transfer is complex. Your options are to accept this consensus, or do a lot more study than you have.
