There's always some resistence when breaking habits. I don't miss Google now, about a year after breaking free. You'll learn new ways to do what you need.
The apps I need (bank and ID) work perfect, my device even passes safetynet. I get updates from Playstore via Aurora. Only thing I can't do is pay for apps.
On a distro like Fedora that doesn't ship non-free codecs, flatpaks makes it a lot simpler. So I really like it for stuff like Firefox and media players.
