What Shotgun would you suggest?

[Ruddyduck]

I don't know how the firearm market is in the Socialist State of Kalifornia is. Anyplace else I wuld suggest looking around for a used Remington 1100 or Browning Silver or Gold. An 1100 with a bit of effort can be had in like new condition in the $400 and under range. I found one that had maybe a box of shells thru it for $365. Browning will being in the $500 -550 range.
Pumps are common and a good value if you put in the effort to become accustomed to them. Remington 870 Wingmaster (not the Express) and Browning BPS ,Ithica M 37 are all good choices.
Maybe not the best for clay shooting (skeet & sporting) but they get the job done (Ohio St. Sptg was won 2 years running by a person shooting a Model 12 years ago) and are stellar performers in the field.
