I have an old bike that has a cheap square taper crankset.

And I would like to attach a crank arm power meter to it that will fit a Shimano crankset.

Is there an adapter that can fit into the square hole and offer grips for the Shimano crank to hold onto or do I have to buy something like a Tiagra or Sora crankset and fit that to my bike? (the crankset would be worth more than the bike at that point haha)

Are you able to replace the entire existing square taper bottom bracket with a compatible cartridge with the same splined fitting? This assumes you bought the power meter already. Of course you need both crank arms even if just one side has a power meter.

The other option is to get a pedal-based power meter instead of a crank-based one.

    A pedal based PWR meter would also be transferable between different bicycles in a matter of minutes with a simple pedal wrench.
