A game of study for comparison might be Victoria 2. It's a grand strategy set in the Victorian period and has a decent economic simulator that the player can influence in a fair few different ways.

A few different ways a player can effect their nation's economy include: unlocking technologies, conquering territory for resources, expanding a nations sphere of influence for resources and markets, electing parties with different economic policies (planned economy vs laissez faire), playing with taxes/tariffs, encouraging certain industries, etc. The economic simulation isn't super deep, but it is deep enough to be engaging and fulfilling to a player who likes these sorts of spreadsheet simulator games.
