Is a wax ring the best technology to seal between toilet and flange?
Since wax is not elastic, slight movement while attaching (or after
attaching) the toilet back on could cause the seal to become broken.

Any better alternative?

Better? Yes, by far.

Fernco waxless toilet seal. Use one once, you'll never go back to the
wax ones again. Even movement of the stool won't break the seal as it
is flexible.

Thanks!
It looks like this type of seal narrows the pipe's inside diameter somewhat.
If added to a 3-inch drain, would it restrict the flow too much?
