In presume you live in Salt Lake City?

Yes I do.

I don't live in Utah, but my experience during my travels has been
that streets are generally signed like "S 900 E."

Not in salt lake city.

All cities in Utah
(that I am aware of) are laid out in a grid and use grid style
addressing (I think you alluded to this in your post).  In the above
example, there is probably also a "N 900 E."  If move the "S" or
"South" (I don't want to get into the expand vs. not expanding
abbreviations here), you introduce a potential ambiguous situation.

There is a North and South 900 East, but they are the same road.  North
becomes South when it crosses South Template.  The only ambiguous situation
is if you give an address of "333 900 E", as this has two potential
locations (one North and one south of South Temple). The correct address is
333 S 900 E".  Hence, the directional prefix is more part of the address.
 In additional most printed maps do not include the directional prefix.  It
is only really found on online maps.

If the road changes names when it crosses South Temple (other cities
in Utah use "Main" or "Central" as the dividing line), then I would
contend that it is a different road, at least name wise.

The road name does not really change. The directional prefix is not really part of the road name, it is not signed that way. When someone asks you what street you live on you would say "900 East" (or sometimes "9th East"), you will not include the directional prefix.

Wash DC has a different four quadrant grid system. 14 St NW becomes 14
St SW when it crosses Constitution Ave.  I don't think anyone would
suggest changing it to 14 St W and moving the "N" or "S" to the
address.

Washington DC, uses a different system, and is a separate case.

I think putting the first "directional" in with the address makes
handling the address more difficult.  When finding a numeric address
it is just a matter of comparison, 850 is between 800 and 900.
Typically anything that follows the address, e.g. "Suite B", just
makes the address more specific, it does not mean the location is on
the other side of town.

Yes it does, slightly. Which is why online maps probably include it. It simplifies forming the address. You simply combine a number with the street names. But a full address is more complicated than that. See

The directional prefix (especially when spelled out) in my view just adds noise to the map.
