You haven't watched any of my 10/10, so watch em.
Mononoke
Barakamon
Sword of the Stranger
Wave Listen to Me

It is on your planning list, but I highly recommend The Tatami Galaxy. In my opinion it's a brilliantly written show with a unique art style that is really worth a watch. My only warning is that some of the dialogue is a bit fast - you'll need to read the subs quite quickly during some segments of the show.
The Tatami Galaxy
Another show I think is a 10/10 is A Place Further than the Universe. It may just look like a CGDCT show but I promise it is so much more, and one of the most emotional anime I have ever watched. It's not a slice of life show, but a perfectly self contained story that I think will make anyone cry in the best possible way.
A Place Further Than the Universe
I'm also a huge fan of Hunter x Hunter!! I can see you started that show and have it on pause. I would say if you enjoyed those first episodes then the rest of the series will hopefully be really enjoyable!

I hope you find some great shows to watch!

Kara no Kyoukai Fukan Fuukei (Series)
MONSTER

Grand Blue

Try redo of healer

Clannad: After Story
Clannad After Story
It's the sequel to Clannad. So you'll have to watch that first.

code geass. a masterpiece

I have a large number of 10/10s personally but is purely because of the amount that I've watched, and while objectivity may somewhat lean my ratings on some, the 10/10s are usually at least somewhat an emotional pick. but because I have so many I'll just recommend a few below for a few different categories of watching.

Not a very handholdy watch so you can probably skip this if you don't want to invest a lot of attention
Koukaku no Regios

My favorite Shoujo of all time
Shugo Chara

Changed my life, and still rewatch it every year
Hikaru no Go

My personal favorite shonen of all time(outside technically Hikaru no Go)
Busou Renkin

Just an absolute blast 10/10
Needless

Arguably Controversial but IMO a 10/10 exploration of the idea
Kodomo no Jikan

Edit: one of these could be on your list by accident, but when I scanned it I didn't see any of em. feel free to point it out and I'd give another thing for that category or similar. and if you wanna request a type lmk.
