I mostly read slash (m/m) fanfics, but occasionally I’ll read f/f or het. My fanfic recs reflect my reading preferences (duh).
What to expect: complete stories, heavy on the romance, happy endings, AUs and tropes which lead to happy endings.
Things I like or have liked in the past that you may find iffy: alpha/beta/omega dynamics, some BDSM, OT3/poly ships, incest, age difference, murder husbands, real person fiction (RPF).
What to not expect: rape/non-con (except perhaps “prior to the story”), sad endings. I nearly put “heavy violence,” but then I remembered Hannibal.
Special note re:broken links: I make sure to download copies (usually epub) of every fanfic I recommend. If a link gets broken, I am willing to send copies of those fanfics for reading ONLY (not reposting). [ty to Isabelle]
Each fanfic rec has been tagged with appropriate tags. My Pinboard has MORE tags (like author) which you may find useful as well.

I use the AO3’s system of rating, because it’s easy. Please note that if you’re under 18, you probably shouldn’t be reading anything above teen+.
a/b/o Dynamics / Alternate Universe (AU)* — Bakery AU, Coffee Shop AU, Mafia AU / Animals (turned into, always were) / BDSM / Crossover / De-Aging / Hurt-Comfort / Marriage (/Relationship) — Arranged, Pretend / Reincarnation / Royalty / Sharing a Bed / Snowed In / Soulmates / Time Travel
I generally count something as AU if the setting is significantly changed from the original. HP fics set in 8th year are not technically AU (to me), unless all the characters were ALSO cats, or something.
Anything around 100k is about book-sized. Comparison: The Hobbit is about 95k words, Harry Potter and the Prisoner of Azkaban is 107k words.
