Why don't you consider uploading it to the cloud?
That is what I did with metamask phrases. I remember the password of my email. And in fact, all I need to remember is the password of my email, I synced everything, so when I log in to Gmail, everything automatically gets synced, and I have the doc where my seed phrase is saved.
I'd recommend that, it is convenient, easy.
It seems convenient but storing your seed phrase on a cloud service is is one of the most insecure way of seed storage. A lot of things could go wrong for you, from a simple account hack where your password is leaked to bigger catastrophic events where the cloud service itself gets hacked and everyone's accounts and their content is leaked where users aren't even informed for a long time while the company covers it up.
I am not the best of coders out there, but I do agree with the picture, and I am confident that my password would be neigh impossible to crack, unless google sells, it which is even less likely
