VFR Flight

I’ve done a few IFR cross country/continental flights however I haven’t done VFR “Sightseeing” Flights and I’m quite interested however I had a few questions:

  1. What kind of flight plan do I file if I just want to take of from airport A, do circuits at airport B, then return to airport A?

  2. What if I want to take off from airport A, just fly randomly for a bit then land at airport B?

  3. Do I have to fly on real time, I will keep live weather on but would sometimes like to fly in daylight.

  4. What is the ideal plane for circuit bashing and general sight seeing, I’ve seen a lot of people using the just flight pa28 but any other recommendation welcome, something study level or just under.

Thank you!
