I have now installed the LineageOS cedric 17.1 (android 10) on my moto g5 and it behaves very well. I installed without the Gapps package and I’m using Fdroid and apkpure as appstore.
So far I’m quite happy with the operation of the phone.
I’m not sure how much work there is too go from the LineageOS package to the /e/ package and what the real objective benefits would be. Any advice / insight /pointers are welcome.
