I’m looking at a Gen 5 G19. Shop can get the normal G19 or the MOS version.

Use will be home and self defense. I’ve never had a handgun with a red dot, but a number of cops I know swear by them for their duty guns. The MOS versions are like $60-70 more, plus the cost of optics. However, I’d probably drop $130 on night sights (which I won’t need with the red dot).
