Actual question further down if you find my post too long. Wanted to give some more background first as to what I'm looking for.
My privacy journey started about a year ago and since then I've tried to find a good balance between privacy and functionality. I've gone from not caring about my privacy at all to striving for almost complete anonymity. Now I'm trying to find a path that is as privacy friendly and secure as possible while still maintaining every day usability and conveniences, e.g. I won't switch to Linux as I don't have the time nor energy to learn it right now and windows offers a reliable gaming experience.
So I just ordered a Pixel 7 and I'm considering installing GrapheneOS on it. I know there are always compromises. My experience often is that more privacy meens less usability, e.g. blocking Google assistent removes ability to voice control when using Android auto; or blocking 3rd party scripts with ublock can be tiresome as you always need to unblock for every new page when they brake. Also I've found it almost impossible to find a note keeping app that is comparable to Google Keep.
So my question is if GrapheneOS is for me? I use my phone for browsing the internet, some shopping, streaming (Spotify mostly), chatting (signal mainly and whatsapp), email, banking and taking photos. I also use sleep as android which is of great importance to me.
Will I be able to keep using most apps? I'm mostly worried about bank apps as I've read it can cause problems. I'm located in Sweden if it makes any difference?
In short: What conveniences should I be prepared to sacrifice?
Also, is it easy to revert back to stock OS if I change my mind?
