Have you tried ‘microg 4 lineageos’? I’ve been using most of my bank apps without any issue through it even with strong integrity failing. Not ideal but it works best for me while minimising google’s existence in my life better than stock android. It even has OTA updates much longer term than my oem. A major caveat for almost all phones is the firmware can basically never be free, and sim networks are designed for spying anyway.
