They will have some guidance around them but they are more around how much time you have and how much stress you can handle. A high FTP alone shouldn't warrant one plan over the other.
The plans will also ramp you up, so if you start in advanced base it will build you nicely into the advanced build.
Without knowing too much about you I don't see any reason why you couldn't do the advanced build when it comes out. 6 hours a week of structured work on the trainer is worth a lot of time outdoors. If you're IM training I don't see how that could be too much work though. You should be able to handle a good amount of stress.
At low volume like this more is more. If you do put too much stress on your body too fast you'll be able to feel it and you can start cutting workouts and backing off a bit.
