I flashed e/os to main and I love it! Automatic blocking of trackers. Clear notices when apps access hardware. Falsified GPS to a plausible location at the flip of a switch. It's still not perfect but it's a big step and very easy to install.
I think Graphene is similar?
Oh that's totally fair! Honestly it's been a really pleasant surprise? I thought I'd have to fight it but even the few Google apps I needed still worked without an issue. I've been gradually sunsetting them one by one and just removed the last one the other day.
I love Organic Maps for nav. The voice is a little clunky but everything is computed offline.
Did you want any help? Tech support is literally my job, lol. I've built an are stack + jellyfin, mailserver and home assistant before for what it's worth.
