@ntnsndr another great option is to get a Pixel phone and install @GrapheneOS on it using WebUSB installer, quite a straightforward installation process.
Compatibility with Android apps is also much different. GrapheneOS provides our sandboxed Google Play compatibility layer:

Can run nearly all Play Store apps on GrapheneOS, but not /e/OS with the far more limited and less secure microG approach.
https://eylenburg.github.io/android_comparison.htm is a third party comparison between different alternate mobile operating systems. It could include many more privacy/security features but it's a good starting point.

GrapheneOS and /e/OS are very different. GrapheneOS is a hardened OS with substantial privacy/security improvements:
https://grapheneos.org/features
/e/OS is not a hardened OS.
They're always on a very old release with partial support. Android 15 QPR1 is needed for full privacy/security patches. Only patches for issues deemed High/Critical priority are backported to older Android releases, and most privacy patches are not backported.
They also lose a bunch of security features.
