I think Louisville is the logical landing place for Moss, but logic doesn't always enter into the equation.
Neither Iowa nor Michigan make any sense. Auburn's QB is in the portal, so Moss could slide into the starting job there with ease, but Auburn has slid down the SEC pecking order the last few years. I think Louisville would provide both the offensive scheme and the team profile to help him the most. Louisville is 8-4 this year, but two of those losses came against teams in the CFP (Notre Dame and SMU) and one loss against a team that arguably should be in the CFP (Miami).
