I use FreeBSD for my daily driver. I now stream games/Windows apps from a dedicated windows VM. It's impressive technology.
Still, I'm in the same boat as many who wish they could migrate their decades' worth of photos with all their adjustments to a FOSS alternative. For me too, Lightroom is the last application that keeps me from dumping Windows for good. It already lives in a Windows VM on a Linux host these days.
I just have my two monitors hooked up to both my iGPU and dedicated GPU, and switch inputs if I want to use my Windows VM. It means things like colour profiles and VRR work as expected too.
