At Case Western, they have an “enhanced” (one could say honors) version of the Calculus courses…
e.g.
There is regular Calc 1 (Math 121) but an enhanced version (Math 123)
MATH 121 (Calc 1) is the regular first semester course in the standard science and engineering calculus sequence. This course covers functions, limits, derivatives of algebraic and trigonometric functions, related rates, applications of the derivative, definite integrals, antiderivatives, and fundamental theorem of calculus.
MATH 123 covers the same topics but is taught with more emphasis on the underlying theory. Students taking this course should have a high level of computation proficiency and a willingness to be challenged

There are also Honors Courses that are part of an Honors Program:
e.g.

I would not worry about what employers think…If you find the material engaging and want to challenge your self…take an honors course. It isn’t like HS where to be truly prepared for good colleges you need to at least be at the honors level.
