nato Is there a website I can reference to make sure the apps that I am using on my Samsung Galaxy S24 would be compatible to use on GrapheneOS?
How well do banking apps work with GrapheneOS? I currently use the Commonwealth Bank App and the Bendigo Bank app for work. Any issues with those apps?
Please look at the pinned posts on this forum. Most apps work fine, only a small number of apps (particularly banking apps) tend to have trouble running on GrapheneOS.
Would I still be able to use Android Auto? I use spotify to play music travelling to and from work.

What would I need to know when purchasing a pixel. I heard something about them having a unlocked bootloader?

You need one of the officially supported devices. To make sure that the device can be unlocked to install GrapheneOS, avoid carrier variants of the devices. Carrier variants of Pixels use the same stock OS and firmware with a non-zero carrier id flashed onto the persist partition in the factory. The carrier id activates carrier-specific configuration in the stock OS including disabling carrier and bootloader unlocking. The carrier may be able to remotely disable this, but their support staff may not be aware and they probably won't do it. Get a carrier agnostic device to avoid the risk and potential hassle. If you CAN figure out a way to unlock a carrier device, it isn't a problem as GrapheneOS can just ignore the carrier id and the hardware is the same.
Other than that, there's the possibility that future Pixels (10 onwards) might not be bootloader unlockable, but its not certain so any purchases would best be done once its confirmed that the device can be unlocked.
