I can only report about whatsapp. I have Google Play Store + Google services installed on my Graphene-Phone and I am using Whatsapp with no problem.
As for Banking App Compatibility, I cannot comment as I use different banking apps than you.
You can check this website: https://privsec.dev/posts/android/banking-applications-compatibility-with-grapheneos/
All the other apps you mentioned I do not use so i cannot give any infos how they work or not work on Graphene.
What I know is most apps that are not using "google certified" should normally work on GrapheneOS.
Some Apps might require Play Services and some apps have bugs that makes them crash by Graphenes exploit protection, hardened memory allocator and MTE, but thats a good thing means those bugs can be reported to the app developer and GrapheneOS has a compatibility mode app toggle to get those apps running.
