Well, I would like to recommend this fic:
Fate: Reach Out
By Vegeta the 3rd
Genre: Mystery/Supernatural
Crossover: Persona 4
Summery: A chance decision leads to an unlikely discovery. The mention of a rumor leads to an unbelievable mystery. And the connection to a long forgotten family leads to an unforgettable experience. Welcome to Inaba, Yu Narukami... or should I say Shirou Emiya? (Co-Authored by Nameless Flame Wielder)
Pairings: None so far

A really interesting fic of Shirou before the HGW. I believe it does a good job at showing his mentality and mannerisms, making his interactions with the Inaba residents' interesting. It also brings up the possibility for a different path for Shirou with the new bonds he'll have to make and experience.
Also just in case, that's a +1 from me for this story
