Fractional scaling is solid on Wayland in my experience. The main issue is not all desktop software has been updated to be friendly with Wayland yet—Electron being a notable offender. For these apps, there's often configuration options via env vars you can pass to the process to force Wayland or XWayland mode. Eventually, this will be unnecessary as the apps get updated, so things should only get better from here on out. I run Fedora 36 and use a TB3 dock for a 1440p laptop I run at 175% scaling.
