That's a cat and mouse game, and some banking apps still manage to detect rooting, and so does Netflix and Google Pay.

Not really though. I've been using LineageOS+Magisk for at least 6 years and haven't found an app that worked that stopped working all of a sudden. I'm using all my banking apps and everything else without issue, and have been for a long time. Doesn't seem like the app devs are hellbent on blocking those willing to use Magisk.

Banking is something seldom enough that you can just run it in a browser, like God intended
