How do I build a resume for service/retail jobs after not working in service for years?

I've been applying for full-time jobs related to my degree since graduating in May 2020, but it's been difficult. I want to apply to service/retail jobs to earn money in the meantime and keep myself from going insane applying to full-time jobs 24/7. The problem is, I haven't worked in service in 4+ years. I have had a lot of internship experience during college, but I'm not sure if they're worth including on a resume tailored for service/retail.

How does one go about writing a resume for service/retail jobs after being out of the game for so long? Is it worth putting in my high school job experience and omitting my internships, or should I include both? I'd greatly appreciate any advice!

Thank you in advance!
