There are a few categories for mutually forced moves-they either end in checkmate, stalemate, or neither. Either almost/all (almost would apply to neither and stalemate) moves are checks or not. Either multiple legal moves are available or just one is. Promoted pieces are allowed and not.
I shall refer to games where not all of the moves have to be check as No-Checkers” for simplicity’s sake. Another thing to know is that since promotion choice is not forced, it and all moves afterward are not counted.
I shall do by best to cover each category. The sections for neither and stalemated are currently in the works. I have done lots of research and spent time to bring this all to you, for our mutual benefit.
Each game shall be recorded in length by plies, or half-moves.
If you can /create or know of a better, already known composition for a category, feel free to share it. If you create it yourself, I shall credit you. Additionally. I would be more than happy if you could find out who the unknown composers are for the unknown ones.
This is the section for checkmates.

Here is an honorable mention
of 9 half-moves. Since promotion choice is not forced, that is not counted nor any afterward moves.

Interestingly, Tim Krabbe gives a variation of the puzzle by the composer, up above this sentence. The source is the same one for the 22 half-mover. This is also 9-half moves.

This is the section for neither.
The only thing of worth to put here, at least to me, is this game, of whom I don’t know the composer here, that was originally provided by Hauke Reddmann in his answer.

This is the section for stalemate.
This is what I have so far. This is based of course on the 18 ply game in the nether section, of course.
