Ok! You got it! Here are some of my all time fav Goge fics on pixiv (that are fairly vanilla and suitable for everyone too)
1. https://www.pixiv.net/novel/series/1439075
This is a 3 part series about Suguru, who has many chances to relive his past but fails each and everyone of them so he gives up on sorcery altogether, and Satoru, who doesn't remember his past but NEVER gives up on Suguru. It's a sweet comedy

This is THE standard HrHn AU goge fic. A story about Gojo who becomes a comedian to make his best friend, who "can never laugh from the bottom of his heart", laugh, and Suguru who becomes a comedian cause Gojo has "someone" he wants to make laugh. Reincarnation + HrHn AU, The whole hipd gang are there, lots of emotional n humorous scenes.

Reincarnation AU, rental boyfriend Suguru! Surprisingly this is a PG fic. It's about Gojo who has memory of his past life and rents Suguru as his boyfriend w the purpose of making Suguru, who doesn't remember anything, fall in love w him and quit being a rental boyfriend. It's sweet and funny

This is THE omegaverse + soulmate fic, srsly I can't say too much without spoiling the plot. It's about Suguru who is bitched from an Alpha > Omega and never really adapts to the change, plus he's barren because of his cursed technique n self-destroying tendencies, so he thinks he's a lousy Omega. Not to mention that Gojo has a soulmate... but that soulmate isn't Suguru. But, spoiler alert, Gojo picks Suguru because his heart and soul picks Suguru and that's his choice, not something that fate decides.

Alt universe where Suguru doesn't defect, but still parts way w Jujutsu tech bitterly and becomes a cult leader. He and Gojo gets in a friend w benefit situationship... the fic is way better than I can summarize it. Yandere Gojo, angst, hurt and comfort and PORN, AMAZING PORN

I'll make more suggestions if anyone wants more... plus lmk if you want spicier stuffs
