My banks technically don't either but after some tinkering with the aforementioned microG they're none the wiser :)
Currently running DivestOS on my second-hand fully degoogled Fairphone 3 and everything works pretty much perfectly (a couple minor things are glitchy but it's only aesthetic). I get 80 % of my apps from F-Droid and the remaining from Aurora Store. Things like my bank apps also work after setting up microG
