Distance into the house is not the issue. You bond the ground and neutral bars to each other at the location of the service disconnecting means. Generally, in a residential service that would be the main (and often the only) circuit breaker panel. But if there is another panel sub-fed from the first, you keep the neutrals and grounds separated from each other.

Chances are you cannot run 10' into the house without having an OCPD on the outside.

A lot of jurisdictions consider an underground service lateral running below the building foundation to still be "outside" the house......as long as you have a MCB at the panel, then no exterior disconnect switch is needed. Fire dept. not too happy about it, but the AHJ allows it.....

True, but the OP did say:
where the panel will be located more than ten feet,once entering the house

This had me wondering if the metal meter box has to have a ground wire on it, esp if it is connected by pvc, or if that is not necessary. i have not put one on in the past, but wasn't sure if this was still the case.

I am assuming you are talking about an EGC.
In a single phase service you only need 3 conductors between the meter base and the service panel. Two ungrounded conductors and a grounded (neutral) conductor. No EGC is required.

POCO installed in CT will not allow GEC through meter unless an OCPD is in it
