Speaking as an experienced desktop .NET Dev, we've avoided it due to years of instability and no real confidence it'll get fully adopted. We've stuck with WPF, which is certainly a bit warty, but ultimately fine. If starting fresh at this point I'd give a real look at Avalonia, seems like they've got their head on their shoulders and are in it for the long haul.
Would also recommend Avalonia. It's truly cross-platform (supports also Linux) unlike MAUI.
My big issue with Avalonia is the lack of native WebView control. In fact, I could not find one at all that would work OK on mobile and desktop.
