Yes, the outer flange was metal. It looked like it was to sit at the very
lip of the flange. The rest of it is plastic. It didn't really sit flush
though. It is above the level of the floor. The plumbing is about 15 years
old. There is some bad wood there, but there was enough (at last glance,
that everything was still secure and firm.

I'm still confused on whether the toilet (and flange) will sit on top of the
ceramic tile or floating wood floor, or whether it will all mount directly
to the substrate and the tiling (or floating floor) will then bump up
against the toilet.

The flange sits on the sub-floor where it is securely anchored. The
tile is cut around the flange, but where it will be covered by the
toilet.

If the plumbing and sub-floor, is a-ok, you should be able to refloor or
clean the bath simply by pulling the toilet off, and you have full
access to the floor material.
