There's really little need for one. If you work for a bit then invest your money in the bank, any money issues go away pretty quickly. Buy all the stuff in the shopping center and that will build up your stats. Work out at the gym and build up your strength. It takes very little time to max out your stats, and I'm not even sure any of them are necessary except for money.
Agreed that it's not essential like it is in more grind intensive games. I don't know of a mod ever being made for this.
To go into a bit more detail:
for money- work at the nuclear plant just enough to start Verde's quest chain (i think 3 or 4 times), buy all the waiter clothes, work at bar a handful of times, invest enough (@ bank) that you earn 200+/day, and you're pretty much set. Skipping through all of it, it's possible to do all that in under 15 minutes from a fresh start if I recall correctly.
As far as stats go, I know there's a low strength requirement for Kyra questline (40ish I think) as well as a high STR req to trigger Mia's first scene (75ish).
I think Aya might require low intel (30ish maybe?) because she rejects your advances outright at the beginning, and after raising intel to 40something the same dialogue option started a scene.
And pretty sure Miranda requires a fairly high appearance score during her questline, I think it was >50 but I can't swear to it.
Those are the only things I can recall that seemed to have stat prerequisites. Raise your strength @ gym, raise intel @ library, and buy fancy clothes to raise appearance.
