So, update report, after carrying around 2 phones for a few days (the new one, and the old naughty googly one):
I've been missing Google calendar and Google maps a lot - turns out I use them quite a lot.
The unexpected ones: Google contacts and Gboard - both things I thoroughly took for granted to the extent that I didn't really think about the fact I was using them.
I've just caved and set up Google calendar and contacts access BUT I've done it through #davx5 and am using the default calendar and contacts apps which came with #lineage.
Long-term I think it would be fun to move away from having #Google manage that data for me (maybe using #radicale and #syncthing? https://forum.syncthing.net/t/how-to-sync-contacts-and-calendars-between-desktop-and-android-without-root/21326) but that can be an adventure for another day.
