All of the above are possible

You have more complexity in your mouth, so naturally, there are more things
which could fail in the future.

Should feel normal.

Should be possible, but the teeth are very thin, so the preparation will
have to be closer to the pulp chamber.

I always elect for supra-gingival margins when ever possible.
