I try to automatically compile a "recommendation ranking" for currently supported LineageOS devices from the official LineageOS wiki data, refreshed daily. It's available here: https://johannes.truschnigg.info/tmp/lineageos_device_toplis...

I recently upgraded from a used beryllium (Poco F1) with a dying battery to a used, but pristine dubai (Edge 30) and have been very happy with that choice.

At least for Qualcomm-based phones, make sure to have the phone's stock ROM provision IP Multimedia Services (IMS) with your MNO/ISP, so that (you increase your chances that) VoLTE/VoWIFI will work also with LineageOS.
