If file size is an issue - you can use Arc Welder which intelligently converts endless strings of G0 & G1 codes into G2 & G3 codes. Cuda has an Arc Welder plugin which does this post-processing conversion. But Cura doesn't do it natively - I can't see that you'd gain much if Cura did as you'd get pretty much the same result at the end. https://marketplace.ultimaker.com/app/cura/plugins/fieldofview/ArcWelderPlugin
