Flange recommendation needed. Old flange rusted. New floor higher than older pvc pipe lip

drain-waste-ventflangerepairtoilet

I recently removed the tile and a toilet for a bathroom reno to discover that the flange was completely rusted and the tile had been installed directly on the plywood subfloor. I removed the old flange with a Drenmel.

I need to install 1/4 inch cement board and then tile so my floor level will be raised by at least a half an inch. Which will be higher than the lip of old PVC flange rim(sorry I don’t know what that piece is called)

Can anyone please advise what the correct product would work as a replacement flange? I was thinking the Sioux Chief Push Tite or something similar. But I’m unsure if I can install those products with the pvc portion of the old flange (that lip the metal ring sits under) still connected to the PVC sewer pipe. All of the videos and diagrams I have seen install directly into the straight sewer pipe.

If you need the extra height, just install a replacement flange that fits inside the existing pipe. There's both screw-tightening (where tightening bolts pushes a rubber gasket out to lock in place)

(Response to edit)

If you can get underneath (as your new picture depicts), you can avoid using an insert flange entirely. Cut the pipe off somewhere below, add a regular flange to a new pipe and just add a new coupler to attach the new to the old. Easier (and cheaper) than an insert.
