I was in that same boat about 4 years ago, albeit for different reasons (security and privacy). So I chose to build my own NAS (I ended up with UnRaid after testing about 7 different NAS Open Source OSs, but they all do pretty much the same. I try to stay away from commercial stuff like Synology and Qnap). I have everything "cloud" running out of it, replacing most cloud needs with Nextcloud + OnlyOffice. I have never looked back. For my other services, there are Dockers for pretty much everything you want to host such as Bitwarden (password manager), Joplin (best notes platform ever, replaces G-Keep) and like 10 other self-hosted services like Bookwyrm to replace Good Reads, Kavita for serving books, Manga and Comics. Can't comment on replacements sold by other companies because I don't trust any of them at all. And I am sorry to be the bearer of bad news on your choice of mobile platform, but you had the best option already in your hands with the pixel you replaced. Replacing the stock Android with GrapheneOS (that's what I chose after a lot of testing the others), CalyxOS, LineageOS with or without Microg (depends on if you still need Google services) and a few others. Apple doesn't have the best privacy record. In any case, everything Google offers has an alternative, but aas with everything else in life, there are trade-offs. Glad to see more people are getting away from big tech, this is the only way they MAY/may not rethink their approach with their clients.
