There usually isn't more that one aircraft at say your 11 o'clock two miles.

The pilots say things like "See traffic at 12 o'clock, but can't tell
if it's a regional carrier or not. Please advise." This sounds like the
pilot is expecting to be able to recognize the plane.

I can say that I've never said or heard anything like that. Like Gig
pointed out, there usually aren't multiple planes in the same
coordinates in the air. If I see my traffic where ATC says it is, I
don't really care what kind of plane it is. Obviously, if ATC says I'm
following a 737 on final and all I see in front of my is a Citation, I'm
going to question ATC (where IS that 737?), but it's generally not an issue.
