So google play services is the necessary evil that I have to keep using even after switching to Lineage. I'm back to using them again, but PlayStore and PlayServices are the only two google apps that I have currently. I try getting most of my apps from FDroid -- my filter for "good" apps is mostly how active the repo is, not great but it works.
I've moved my mail over to Fastmail, and looking alternatives to Google Drive (Backblaze B2 is one that I'm thinking of). The problem with all of these non-google alternatives is although they're only slightly inconvenient for me, they're almost impossible for my family to use (B2 for example doesn't have an app).
