Sound like a great journey you have taken. Well done. I did more or less the same transition, except iPhone bit , and using the same apps you use. This difference is that it took me 10 years to complete this journey in full but that reflect my age more than anything else. Gen X
GrapheneOS can make a difference here I would say. As long as a you don’t fill it with loads of crappy socials apps. These are the real killers.
