The superconducting properties of a two-dimensional metallic system with arbitrary carrier
 density and both local and various types of the indirect boson-exchange attractive interaction in
 the cases of s- and d-wave pairing are analyzed and reviewed at T = 0. In particular, the possibility
 of a crossover from the Bose—Einstein condensation regime to Bardeen—Cooper—Schrieffer-like
 superconductivity with growing carrier density and changing coupling in the case of different pairing
 channels is discussed. Gaussian fluctuations of the order parameter are taken into account, and
 the carrier density dependence of the gap magnitude is studied. The role of the form of the
 interparticle attractive interaction in the physical behavior of the system is also considered.
