what is a type with value semantics? and how does it differ from other types?
should types with value semantics be passed by value to a constructor or method instead const T& ref?

Why don't you do some fucking work yourself for once and write up a little essay telling us what you've learned about "value semantics" from googling.
it's a general computer science concept, see https://en.wikipedia.org/wiki/Value_semantics
as far as C++ is concerned, Lakos said it best at Cppcon 2015 (and elsewhere, this is just one of the more accessible links)

no, that has no bearing at all. see https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#S-functions for argument passing guidelines.
