I suspect you'll have to use the same method that a lot of people use: Trolling through reviews on different films and developer combinations, and looking at online scans (which can be misleading). As Ralph mentioned, it will be subjective since one person's beautiful grain will be someone else's problem grain.
Tri-X developed 1+25 will do the job, it looked nice and grainy the few times I've tried it. Back then I was shooting Tri-X at box speed. A lot depends on the film format and lighting too. 4x5 Tri-X in Rodinal will look vastly different than 35mm.
