I still love my Pixel 6 and I am thinking of grabbing a used Pixel 8 to run GrapheneOS.
I am not one to chase the latest benchmarks. Any phone made in the past five years or so is perfectly capable once you take the bloat out.
Edit: I found a great deal on a Pixel 10 and have ordered it.
List of potential workarounds for problematic apps: https://discuss.grapheneos.org/d/8330-app-compatibility-with-grapheneos
Also includes a link to an unofficial list of known working/not working bank apps. If the app still doesnt work there is a link to documentation for the app developers on how to implement support. It is good to include it if reaching out to your bank about this issue.
