I couldn't find a good theme for me though, which led me to create my own. As base I used Yaru Blue Light and then fixed some things especially when compositing is disabled and redesigned the panel and whisker menu. I also created xfce-notify4 and xfwm4 themes (there is also an xhdpi version for 4K screens) as well as a nice icon theme that fits well in my opinion. I'm really happy how it shaped out, so I decided to share it with you.
