Maybe there's a way to install both but turn one off and the other on?

Yes. There is. In fact, this happens automatically when you install and run a JACK App.

I just think this is suboptimal, since, as far as I know, there is a way to make both work at the same time. So, at least for me, having this by default would be a really nice thing to Fedora Workstation.
