I may be wrong here but wasn’t Nixon’s pardon related to the indictment inherent in the House vote to impeach, and/or Nixon having been named as an unindicted co-conspirator in the Watergate cases?

Impeachment action was dropped after he left office, there was no real effort to hold him accountable after he left. Preemptive Pardon took away any future Federal prosecutions.
