The idea of crossfit appeals to me, but as I am short and lean, I'd rather put in time at gym to gain muscle mass and strength first. If I wanted to enter the Crossfit Open I would not currently cope with the weights that the men have to lift overhead. e.g. lifting 42kg for 10 x overhead squats, etc... IMO, the ideal crossfit height and weight for men is around 5'10" and 75-80kg with the appropriate strength levels to go with that build.
As I can't do anything about getting taller, all I can do is try and get my power to mass ratio off the charts before I have any hope of excelling at crossfit

Two of our coaches (guy and girl) are a lot shorter than me. Currently I'm around your ideal 5'10" and exactly 80kg, if that gives an idea. So don't let that scare you
Also don't forget that you can scale your weights down to suit you. Everything in CrossFit is structured so that it can be scaled up or down for anyone. Hell even now I still wouldn't dare competing at the games as I still struggle at the ladies Rx levels, never mind the guys.
However that said, the best is to follow your own instinct. Else you won't feel like you own the process and quit soon after
