#[7] mentioned if you're running a bunch of apps you might have to open various ports.

Presumably, the more ports you open the bigger your security risk. Last thing you'd want is to compromise your Bitcoin node. I think setting up a separate VM for each of my lightning and Bitcoin nodes would be a decent compromise. Would also be able to solve my windows/ubuntu issue as well. Admittedly I have very little experience with Ubuntu so the VM route offers a bit of safety net I guess
