I would say just get your PGWP and search for a job you like. You will have enough time to apply for your PR and at this stage finding a job is more imprtant.
You will eventually be able to apply for various PR programs if you have a full time job and one to two years of work experience. Of course, if you find a quicker path to PR you should take it, but I believe you don't need to worry too much about this at this stage.
