FEM is typically frequency domain, hence it's good for structures with high Q such as cavity filters, where you know the resonance a-prior. The time domain methods are nicer for transmission lines and antennas since the whole response can be computed at once.
CST has many solvers built it, not just FEM; the time domain is the most popular.
