Did this using iodéOS which is a LineageOS distro with more degoogling and os level adblock and filtering build in. Works very well and has been stable for about the 4 heads that its running on my FP4.

Check out iode.tech as well. Like /e/OS, also a lineage OS variant but with build in firewall which you can customize (or turn off). Fast security updates and great default informed FOSS apps (unlike /e/OS).

The combining of subscriptions i s exactly why I like liftoff as well. Used a couple other clients, but Liftoff seemed the most stable and easy for me.
