I'm not sure where "getting started on Ham radio" got into the picture? FWIW, if you WANT to get into HF radio with RTL-SDR get an upconverter, it'll map the HF radio region into something the RTL-SDR dongles can hear. Yes, the RTL-SDR dongles don't have the best sensitivity, but they certainly don't "only receive strong local stations" in my experience. Maybe you had some bad hardware when you tried them?
