I think in my mother's situation, the pleated filters restricted the
air flow so much that the coils froze up.

Maybe the newer units are engineered to use pleated filters.

If the coils are freezing up it's probably because the coils need to be
cleaned.

In my current home which I bought in '02, the air handler was
(replaced it in '05) 18 yrs old and ran fine with pleated filters.

Coil was recently cleaned before use of pleated filters.

Use of pleated filters in this system = freezing of coils

Use of fiberglass filters in this system = no freezing of coils

Do the filters slide into the unit itself or do they go in the return
grill?

Filters go in what I call the intake.

Ground level framed in box leading to inside unit in the attic.
