I saw a comment asking this question earlier, and I wanted to share my thoughts on it. (This was originally a reply to that, actually)
I think, at least for me, that Phase 4 is themed heavily around grief and how various characters respond to it. For example, Wanda's inward denial of Vision's death was what caused the Hex, and also what ultimately ended it. Shang-Chi demonstrates the dangers of holding onto departed loved ones too hard, and how that can drive someone to madness. Hawkeye addresses the death of Natasha, showing how it's affected her sister and Clint. We see Peter's burning hatred for the Goblin after he murdered May, and we see how her death gave him the push he needed to
