What advice do you have for a 4th year student with genuinely no experience on what they should prioritize and what they should do?

So currently my only experience is university requirements and a 3.0 and for personal reasons there were a lot of factors at play in the past 3 years as to why experience was limited or hard to get but I have ample time to do anything now and I really wanna do whatever I can. I'm a bit directionless so although I have aspirations to do as much as I can, I also don't know what that entails.

Also should I mainly be applying for jobs now or internships that would happen after I graduate? (I am currently applying to both)
