Well your derailleur doesn’t know the difference or care wether your 7-8spd is a cassette or freewheel. Which one you need is based on the hub. That will be largely affected by the price of said hubs or wheelset. 7 spd freewheels are still plentiful because they’re still being manufactured. A lot of cheaper bikes in your price range like cruisers and hybrids are still being equipped with 7 speed systems.
