- SI unit support, including input

- CRC calculation

Were there ever any calculators designed for engineers like me?

It is difficult to add anything new to all of the above. Calculator for the ages is unlikely to be released now. I would recommend some modern CASIO: you will find almost everything in it except the built-in formulas for calculating electric circuits; these calculators are cheap and relatively durable at the present time; the easy-to-call soft menu allows you to work with the necessary symbols/conversions to 1...3 keystrokes.
There is a spreadsheet mode, support for SI units and non-system units.

Casios are very good. The colour ones have better screens which makes the text more readable, although TBH all calculators are pretty poor on that front.
