@Park Soo Jin'Twice Lucky' (warning: incomplete) and 'Second Chance' both get into politics and business. 'Retreads' gets into space.
'Emend By Eclipse' has a lot of money-gathering and business, but relatively small in total amount, enough for a comfortable life but not a large empire.
'Magestic' has a large empire, but no sex to speak of. Lots of politics, though.
'My Second Chance' seems to go where you're looking, but I confess to not having read it yet.
I'm sure I'm missing some others.
There are quite a few do-overs that don't do a lot with politics and business, at least on a large scale. If you're interested in ones that focus more on personal growth than on empire-building, there's an entirely different set of interesting recommendations.
