It mostly just has to do with comfort level it can feel very awkward fighting with your dominant hand forward or back.
A lot of times you will see a grappler put their strongest side forward to help with take-downs and clinching and with their weak hand back they gain near equal striking power with their strong hand.
And on the same note you see strikers put their strong hand back to gain even more power in their strong side attacks and they are not as worried about grappling.
In my case I can fight with both stances but I fight completely different from them.....I'm right handed and my strong hand lead lets me use more spin kicks and elbows ect... and feels more comfortable wrestling with my strong hand forward.
My southpaw I can't use spins as well but I'm more comfortable clinching and my Muay Thai overall is cleaner but my wrestling attacks feel weird.
I attribute my own comfort level in each to my strong leg, With it forward I have a more stable plant to spin or drive for takedowns from while with it back my weak leg is my plant for those things and it doesn't feel as stable.
