Spotify is a big ask because google would have to port widevine (the web DRM.) I've been switching to sound cloud because of this. I'm guessing you're from Europe and that's why your bank needs an "app" instead of just having a website. Here in the US think or swim (the fancy Canadian robinhood style UI for stock trading) works fine in icecat if you turn off librejs.

I think everything else is there. Also Linux games are generally better than Android ones IME. (although I haven't run any besides nethack on my pinephone.)
