I would like to upgrade from the stock 500 watt to a 650 watt PSU. Are there any specific dimensions I have to pay attention to or would any 650 watt PSU fit? Thanks.

    Your stock supply is the standard ATX form factor, as is most of the PSUs on the market. You should mostly be looking to make sure it's got enough connectors to match your power needs, so if a new GPU needs two 8-pin power connectors the supply will need to have both.

    Would a Corsair CX650M work with a RTX 3070? The 3070 uses a 8 pin connector.

    I believe the RTX 3070 uses two of the 8-pin connectors for power, not one, though I may be thinking of the 3080... Yup, just checked on NVIDIAs site, two connectors for the 3080, one for the 3070. 750W for the 3080, 650W for the 3070. So you should be good to go with that Corsair.

    Would a Corsair CV650M also work? I'm pretty sure the only difference is modularity. Does modularity matter with this case?

    Modularity doesn't make any functional difference, it just allows you to have potentially fewer wires in the case since you only install the ones you actually need.

    The stock power supply in this build seems to have the fan in the back where the power connector is, the corsair ones I looked at cool from inside the case. Is there enough ventilation if I upgrade to a corsair?

    Ventilation is essentially the same either way, that's based on air volume moved through the supply, but the large fan diameter on the Corsair might allow the same air movement with lower fan speed, so it could be quieter.
