I remember watching the anime right as the first season was airing and think I stopped at the episode where Yuji and Todo were tag-teaming Hanami(?). It was literally 5 years ago. That was my first and last exposure to JJK (besides minor cultural osmosis of occasional circlejerk brainrot and some inevitable spoilers, stuff like Gojo's memed death).
What would be the optimal way to proceed? Read through the manga and then jump to the anime?
