You mentioned one in being with Max. As the dev already stated, you can choose not to be with her, and she'll just remain as part of the story without being a love interest. Also, avoiding the content you listed, is a significant choice for people who don't want to see it. Depending on how much they like it or don't, having that choice can indeed be very meaningful.
As for what you said in your post before editing it (about avoiding being with the large breasted women), that would defeat the purpose of the main storyline, and what Micah has recently awakened with his genetic Heritage. Basically means that you aren't getting the point of the story.
As an example, let's say someone hates feet content. While choosing a VN, they go through an original post, read the dev notes, check the tags, and see that footjob is among them. If it isn't marked as optional, they might choose to skip it. If while going through a VN there are scenes with foot content that can't be avoided, they might skip past it and hope they don't miss any important dialogue. If it keeps happening, they may choose to stop reading that title. However, considering what you said, you're trying to avoid content and scenes that directly tie into the main storyline and plot. Seems a lot more significant and meaningful than whether or not someone went to the movies.
If it isn't to your taste, that's fine, feel free to explore something new. Seems what you're looking for, unfortunately, won't be found here.
