It would look outstanding for broadcasting assuming of course good lighting, production design etc.
Not sure if you are understanding the 30p vs. 24p concept though. 24p is the more film looking format- it closely emulates film which runs at 24 frames per second- hence 24p. The camera then adds a 3:2 pulldown to derive a standard 29.97 NTSC signal that can be played on any TV and edited in any DV-capable NLE such as your M100. This is based on the telecine process used when real 35mm film is transferred to video.
30p is another format altogether which basically shoots at 30 frames progressive frames per second. The result is also a 29.97 video but with a much different aesthetic quality. Personally I dislike it as it looks like high speed shutter video to me rather than nice film. I’d recommend sticking with 24p. Once you have the camera you’ll understand a lot better how it all works.
As for the 16:9, that is definitely an option on the 100A. It really comes down to what suits the story best- a ‘widescreen’ look or the standard, square 4:3 picture. You may also wish to check with the broadcaster for their aspect ratio requirements as this is often an ongoing issue.
