I've got an SPR of 4 and an overpair! Commitment seems fine barring some weird activity or a freaky flop (or ace high flop)

I'm starting to let decisions like this get made by the AF (not sure this is a good idea). On what little info I've got, villain could be on a diamond draw, have a funky pair/draw hand like AdJd/KdJd, and sets. Is shoving standard here? Is this is fold if villain is passive or much tighter? Comments on preflop raise-sizing are also welcome.
