I've been working my way down this path. Fastmail for email and CalDAV/CardDAV, DavDroid to sync, K9 as my email client, OsmAnd for maps, Firefox instead of Chrome. I try and remember to use SkyTube not YouTube but it isn't flawless. I use KISS as my launcher on Android. I still haven't eliminated Google Photos, I do appreciate the free sync on my Pixel 2 XL for peace of mind, Google Translate is still super useful for offline translate and the camera translate feature and I haven't yet been able to replace Google Maps for transit instructions. I still use a Chromecast which I guess is next to go, maybe I'll actually setup a HTPC of sorts, or perhaps just use Kodi on my Xbox One S as that seems to work well enough.
