Welcome to the community. Looking forward to seeing what you put together.
75g will give you lots of options and scope for your first aquarium.
Are you after some specific recommendations (brandname model etc) or just some general recommendations (filter type, light, heater etc)?
Link to thread containing some useful information for new fishkeepers if you havent already found it.

If you havent already looked into it, a basic understanding of the nitrogen cycle and how to cycle a tank will help avoid issues down the road.
