What are your thoughts on clipless?

My trusty flat Five Tens are at the end of their life and I'm in need of new shoes. I ride SPD with my gravel bike and think my current clipless shoes for that are amazing.

That gets me to think maybe I should just ditch my flat pedals on mtb and get clipless. But I'm a little hesitant because of added risk of falling.

If you ride clipless on mtb or especially if you ride it both gravel and mtb, do you have any tips or thoughts to share?
