A typical 3-bet range is going to be 8% overall no position in particular, a reg is going to have a wider range 3-betting button opens from the blinds. You never really put any stats in or reads so I'll just guesstimate.
Hand | Pot equity | Wins | Ties |

12% | 59.78% | 353,099 | 11,127 |
This range gives us 40% so easy call pre. Your good so far, especially with position.

We hit middle pair plus an OESD which is not bad. This leaves us with two decisions, either shove flop or call and play turns. There is a flush draw out there where we don't have a single blocker too as well. If this board was rainbow or had clubs I would be snap shoving. Since we don't have spades or any backdoors to speak of really I'd probably just flat and play turns. Overall shoving isn't really that big of a mistake, against a bad reg you could get them to incorrectly fold Aces without spades or any gutters.
This is a pure math spot so I highly encourage you to play around in PPT or odds oracle/juice.
