The solution is a de-Googled Android running an AOSP-derived distribution with an enclave (or 'second space' or 'multiple personalities') for those few Google or Google-dependent apps. You can either use one of the second space/enclave/container apps to create such an enclave or you can enable and disable the apps before and after each use (which is what I do). It is always worth trying those apps on a Google-free device since many of them work fine without having any Google services installed even though the complain loudly about GSF needing to be installed for them to work correctly - the Swedish BankID tool is one of the latter, it always produces a popup telling me it won't work without Google Services but does its job once that popup is dismissed. Eventually there may be a non-Android 100% free software alternative but as it stands now the above solution works fine and keeps the data vampires from your door.
