GrapheneOS on devices that can run it, LineageOS on devices that can’t.
I’m keeping an eye on AXP.OS since DivestOS has stopped being developed.
That is, of course, if you’re only counting Android and not Linux mobile. If you are, then I’d add PostmarketOS to the list, though it’s hard to find a device that can be used as a daily driver yet, though the Fairphone 6 is very close.

Seems like Jolla phone (or its Sailfish OS on a Sony 10 III) belongs to that group? I haven’t tried it.
I’m not a big fan of SailfishOS due to its proprietary userspace.
