I think if you re-read your post you will see the answer.
The things left on your to-do list are, as far as I can see, the things that are emotionally hard or very upsetting.
You did not mention when your husband died, but that is not really relevant. Judging by my own experience, the things that meant most to my husband, are still in this house, 2½ years after his death, even although I know he would prefer them to be given to someone who wants and can use the things, I neither know how to use (tools) or want to use (cameras).
But I am only just (about) ready to deal with them now.
