The guided installer will resize your disk volume and set it up for dual boot by default. It’s Fedora based and uses KDE Plasma which is a great user experience IMO. Admittedly, I only booted into it to briefly kick the tires but the install was a pretty smooth process. This page details what features are still missing so I’d suggest looking there first to ensure you’re not missing anything critical. For me, missing USB-C monitor support is a deal breaker.
