Alas, the "Blacks" article is pretty near useless as each state has its own restrictions on felons. The gun ban is a federal law (though also covered by state statutes).
Addressing, PA specifically. PA restores the voting rights automatically at the completion of the sentence. Pennsylvania does bar certain licensing from felons. Trying to be admitted to the bar, for example, is going to be difficult. There's no prohibition on felons holding public office in the commonwealth.
Outside the law there may be some further restriction. Crimes of theft will certainly bar you from holding some of the industry self-regulated positions (banking, financial advising, etc...). Certain countries like Canada will bar felons from being admitted (even for visits) until they have been deemed rehabilitated. Other countries have similar restrictions (Australia for example).
I would NOT involve dad in any hunting or any place where a gun might be stored even in your safe in his home or even as driver or camp cook Absent a long talk with you present with legal counsel familiar with gun issues in his fact pattern.
It is very likely you are a tenant in his home and he cannot lawfully boot you or lock you out if he relapses or gets mad ..Absent due process of eviction
..but that's not very much long term protection for you. You might be wiser.and safer to have a written long term lease for sole occupancy with Dad for this home for say for 5 years and a RIGHT to renew for another 5.
