My Macbook Air is running very slow.

My 2020 Macbook Air is running very slow, especially upon startup. This has been an issue for a while. II use my computer mostly for school, which conists of google docs, word etc. I have downloaded Etre Check and run a report. I will attach it below. I read the report, and I know I have low disk space and the other minor issues, but I'm not sure what to do about that

Any tips on how to clean this up and improve performance would be much appreciated. I'm not against a reset, just not sure how to do this without getting rid of everything.

Thank you,

Oliver H
