D76 or the Ilford version called ID-11 is almost considered the "Standard" developer, that all others are compared to, so it is a good choice. The two are identical for all practical Purposes.
ID-11 / d76 is listed as a recommended developer for almost any film on the market, even obscure Chinese and eupoean brands.
The other popular ones are Kodak's HC-110 and Rodinal. Both of which are Highly concentrated liquids which are mixed up just before use. Some folks find they are more convenient that way. Rodinal is known for Very high sharpness, but also move visible grain. But If you have ID-11 already you are good to go. One or the otehr of the Kodak or Illford D76/ID-11 developer will be less expensive depending on the local market
As far as Film, HP5 is an excellent general purpose B&W film. It is often a few cents cheaper than the FP4, perhaps because many photographers use it as their only film. if you are planning to only go to 8X10 prints I don't think you need to worry so much about the grain.
