Depending on your system, it’s a debatable decision. While exporting 4K saves processor power by not resizing, it utilizes disk throughput and needs to write far more info.
The 1080P version would use less disk throughput and storage, but need processing for resizing.
Also, why use a 1080 timeline? Unless you’re reframing shots, just set your final size in output.
