Privacy benefits of Custom roms - Feddit

So recently my moto G60 reached the end of life with respect to security updates. That was the reason I was using to prevent myself from switching to a custom rom(actual reason is laziness). This phone has rom support for pixel experience and lineage OS. So my questions are if pixel experience has any privacy advantages when compared to the stock rom the phone ships with¿? Also if I flash GApps along with lineage OS will all the privacy advantages I get with lineage disappear¿? I might need Google play services for some banking applications.

The only way to use google play services and retain any privacy is to completely sandbox them, and the only OS that actually does this is GrapheneOS.
as you didn’t mention Calyx, are there any security/privacy benefits of using it?
Calyx with Micro G does have benifits, but isn’t quite as good as sandboxing, and also doesn’t have some of the other degoogling and security Graphene does.

DivestOS permits you to run MicroG as a user app, so it can be run within a user profile (e.g.the work profile).

How do you think this compares to the Graphene approach? (This stuff is above my pay grade, hence the question).

micro g, just like google play, is a privileged app and will have special access to your phone. This is just swapping one middle man with privileged access for another.
