No that is not what angular size distance is defined as. It is the distance in non-expanding space that an object should be at to have the same angular size that an object in an expanding universe actually has at that redshift. Look at the scale. For example at z=10 and the default parameters...

No, if you look at cosmology calculators like New Wright's it gives angular dimensions at any redshift. JWST is measuring angular radii at confirmed redshifts up to around 12.

Good that you covered the theoretical paper on the non-expansion of the universe. But your readers should know there is great observational evidence against expansion and the Big Bang hypothesis. Observations are the key test, after all, of scientific validity. See here: Monthly Notices of the...
