Love that list, things I really like in movies and books personally though is when it isn't obvious, or if it's implied but not said. Love it when sexuality is represented or shown, but in my stories at least, I sort of want to try and make sexuality and gender that isn't cis or straight normalised. There are maybe 3 characters in my story that I will probably write saying their sexuality at some point, mainly because the main is somewhat battling with his bisexuality, his boyfriend who is gay, and maybe another if it is relevent. But I won't hide their sexualities. Jack who is asexual loves to build and design incredible buildings and structures, despite being homeless and having ADHD which makes this love quite difficult. He has an aesthetic attraction in that he 'likes' to be around certain people more than others, but he doesn't want to be with anybody (however he can have a romantic attraction, and has before, but he finds this to be quite rare). If I wanted to say this then I'd probably bring it up in conversation in a way like, if they were talking about previous exes, and it came to him I'd imagine him saying, "I actually really loved my ex-girlfriend. She had an amazing way with words, every one seemed to curl at the end with excitement. She had this way about her, like you could just run up and cuddle her all night… but she wanted something that I didn't, she didn't understand, so she left." - "What do you mean?" - "I don't know. I guess she loved me in a way that I couldn't understand, and I loved her in a way that wasn't enough for her."
I like this in books just as much. But, I think you should try to either show, say or refer to their sexuality at some point. Not like how JK Rowling does it, with the same case, she has stated that Charlie Weasily is asexual, but with no written or shown proof. It's nice, but it doesn't feel real. Anyway this is just my opinion haha :P
