Not TS, but I have similar thought to him. Just recently, I bought a used Samsung A52 4G phone, which is supported by LineageOS.
I am not a LineageOS user, but I own a 5 year old Xiaomi phone. The latest Android version for that phone from Xiaomi is stuck at Android 9. It now runs Android 13 on /e/OS, a fork of LineageOS, and I have a good experience with it.
The biggest problem with /e/OS is the launcher (Bliss).
The launcher does not seem to be able to do app shortcuts, particularly to make a shortcut to an incognito browser tab. Widgets are also confined to a separate page. [Please correct me if I'm wrong.] It's really trying to be an iPhone in some constraining ways (stressed by the Settings icon).
