I would recommend Suzume no Tojimari as another Makoto Shinkai movie. It will take a while to get released (or for it to get pirated in watchable quality), though I felt it was the most enjoyable Shinkai movie I have watched compared to Kimi no Nawa and Tenki no Ko.

Those who say the ending is depressing are missing the themes of EOE. As an Eva fan, I agree that 3.0 + 1.0 is good, but EOE is even better, and I would say it is a timeless classic.

I don't know if by your comment you mean you haven't watched NGE at all, but I would recommend doing so since it is a classic, and 3.0 + 1.0 is at the top of your list. Some parts are a bit dated, and the budget runs out near the end, but it is still a great anime with a great ending with EOE.
