Almost a year ago, I blogged about the apps I use (or recently did but might be useful to others) and my story of liberating myself from Big Tech. It's mostly in prose form, but ends with a nice list of apps I use on my de-Googled Android (now Pixel with GrapheneOS).
I honestly don't trust it for conflict resolution. I keep data that is edited in multiple places, potentially simultaneously off of it and use git instead. I've had one minor incident with corruption in the last ~year, although I already can't remember the exact circumstances. Large files are no problem at all, I've even streamed movies off of it.
That's a major sticking point, but I am yak-shaving so hard that I ended up in a complete re-build of the static site generator and am currently in the middle of that... RSS hopefully coming in a few months once I find time to finish that process.
