I took a look at your implication requests before I saw this post, and I thought about the distinction between "awkward smile" and "nervous grin" as well. I also found a fourth, pretty similar tag that I may as well include: fake smile. There's a lot of overlap between all of them, but I think each can be distinctly defined. I wrote out descriptions for each that I may add to the tags if you think they're reasonable:
Awkward smile: A character smiling in an unnatural way.
Nervous grin: A character's nervousness showing through the way they smile.
Forced smile: A character is being coerced to smile through physical or non-physical means.
Fake smile: A character smiling unauthentically.
There are definitely images where multiple could apply. The tags are definitely messy though.
