LineageOS is just fine if you have a well-supported device. If you need to run proprietary apps, you'll need MicroG (which runs just fine as a user application) and the Aurora store.
Unfortunately, now that CalyxOS has died, the other choices are all forks of LineageOS (Iodé, /e/). The long-term hope is for a non-Google Linux system with all of Android running in a sandbox (something like Waydroid), but that's not ready for everyday use yet.
