Hire a Cessna 150 or a 172 and practice crosswind landings up to the AFM limit which I think is 12 knots. Make sure you can do them perfectly before you start instructing on them. Very few basic CPL pilots undergoing an instructor course can handle strong crosswinds with confidence and they are rarely covered on instructor courses. One or two crosswind landings on an instructors course does not necessarily make you competent at them.
The generally poor standard of crosswind landings in ab initio aircraft is because some new instructors are afraid of doing them and when the student has a go, it becomes a case of the blind leading the blind. Asked to relate how he was taught crosswind landings in a 172, a student said he was told to crab into wind on final by using partial rudder to "skid" the aircraft into wind all the way down on final.
Asked to describe how his instructor told him to do an actual crosswind landing, the student said he had no idea because the instructor never did a demonstration and he didn't have a clue what the instructor was on about. He later obtained his PPL, but was never asked to demonstrate a crosswind landing by the ATO and admitted he could not describe how a crosswind landing was conducted.
