Why, yes, the various S&W J-frames are the perfect pocket guns. I prefer the 638 & 649. I have toted quite a few pocket guns (autos & revos) and all others are relegated to backing up my SW638, these days.
I think you are missing out on the KILLER ACCESSORY for J-frames and other snubbies:
Crimson Trace Laser Grips

I am partial to the boot-grip variant (LG-105) but you may be more a LG-405 kinda guy. The larger grips from CT (or anyone else) on a J-frame means you ought to upgrade to a K-frame.
The CT laser grips are the bees knees for shooting a snubbie in low light situations and for dry fire training at home. I, too, appreciate pretty wood, but the J-frame is more about the function than fashion.
Of course, my preferred carry is a 1911, but reality intrudes and I carry the J-frame about 50% of the time, so I resolved to get better with it. A J-frame makes you apply the fundamentals. If you do so, 5-gal buckets and full size silhouette targets can be hit at 50 yards, once you get elevation down.
As for ammo, I used to be a Buff Bore/ Underwood aficionado. Their nuclear 158gr +P LSWCHP-GC was my go-to. After losing the use of my dominant arm for a while, I switched to target wadcutters. My arm is better, but I have stuck with the wadcutters. Maybe I am getting old, but those wadcutters shoot so well and with so little recoil I don;t need anything other than a boot grip shaped grip.
