Solo female travel safe in Oregon?

Hello! 👋 (27F) I'm planning to do my first ever solo trip. I ll be taking a flight to Portland from TX and take it from there. I'm planning to stay about 3 days. I'm a hiking and nature lover, I would love to visit Cannon Beach and some other natural places, but I'm very concerned about safety regarding transportation, stayings and hiking/exploring these natural places alone.

Any tips/advice on how my itinerary would look like for 3 days?

Would it be better to rent a car or go by bus/uber lyfts? Are hiking trails safe for solo females?

Any recommendations for places to visit, restaurants and hotels?

Thank you in advance
