Generic solders from Radio Shaque etc. is about what you need for general
soldering needs. There are also specialty fluxes that are Acid, Rosin and
Alkali base depending on your specialty application. Flux is basically a
cleaning solvent incorporated into the solder (hollow core) or applied by
brush or squirt bottle.
Since every body is trying to make an extra buck on every sale there are
also solvents for removing extra flux.
Over the years I've done quite a bit of silver soldering, liquid flux
welding (nickle silver) and it gets complicated the more you discuss it.
One of the tricks to soldering is to quit with the heat before the solder
runs back under your insulation and solidifies making your wire brittle
at the connection.
