Hey Brian! Welcome to the addiction lol. For a 3/4 acre pond focused on big bass, here are a few quick thoughts:

Forage: Definitely do both. Fatheads are great for the start, but gold shiners get bigger and give those bass a real meal once they grow.

Timing: Give the forage at least one full season to spawn before you drop in the LMB. If you can wait a year, it's even better.

Bass choice: F1s are solid for growth, but in a pond that size, you don't need many. Maybe 30-40 tops if you want them to get huge.

Feeding: 100% yes to feeding the bluegill. Bigger bluegill = bigger bass. It's the easiest way to jumpstart the whole food chain.
