LG phones tend to lack good support for roms. That is probably not true for every device but I personally would avoid them along with Samsung. However, if the device is listed on Lineage OS wiki it has maintainers and support so it should work decent at the minimum.

From a brand perspective I would look at the device page and find the manufacturers with the most devices. Companies like Google and Motorola Mobility are good examples.

There used to be a really good website that allowed you to filter Lineage OS devices to find devices but I forgot the URL
