Rim size refers to bowl diameter, height is 15 "
No, the floor flange seal (e.g. wax ring) is not included.
If you mean the base that attaches to the floor, it is roughly 10 inches wide but the front is not square, so that dimension is a few inches back from the front.
Options for the seat are oval or round. It will extend the bowel a bit further out. Measure where you want to put it From the bottom of the Home Depot pages for the round and elongated - height, width, and depth of your option. round: Product Depth (in.) 15 Product Height (in.) 30 Product Width (in.) 27.75 elongated: Product Depth (in.) 15 Product Height (in.) 30 Product Width (in.) 29.75 Hope this helps.

You probably just need to adjust the water tank level to where it will work as it should. BUT make sure that little black? hose goes into the pipe/spout as it should to fill the bowl normally.
You are correct. The toilet's tank lid (widest part of tank) is 15".
This toilet is pretty shiny, not matte.
Approximately 28". I have a 12" rough in (the distance from the wall to the center of the drain) and the tank lid is less than an inch from the wall. With those measurements, the toilet measures just over 28" from the wall to the end of the ring.
That height seems to be the height that could go either with the standard height, or the comfort (handicap) height. I'm 5'6" and have the standard height toilet. It works well for me, but I'm not sure if I was 3" taller, which would be better. I tend to think I'd still prefer the standard height, but it may be according to what angle one wants their legs to be at while in use.
