Welcome to the forum. Phantom's are getting pretty much old hat, DJI doesn't sell them anymore, but you can still find them new from few vendors. I have a P4 for sale if you're in So. Calif. I suggest you consider a Mavic2 if you can afford it. I don't recommend MavicPro due to the poor lens, IMO.
I've flown most all DJI craft, except for their Wifi drones (Spark, MavicAir, Tello, MavicMini) because Wifi communications technology is sub par for range, usually less than a mile. I don't expect to ever buy a Wifi drone. With ideal conditions some of these craft with "enhanced WiFi" can go more than 1mi, but it's not reliable IMO. As a noob you need to know that DJI's lightbridge or OcuSync communications will reliably provide 2+ mile range, which really comes in handy sometimes when you need it. The purists in this forum will say you don't need that kind of range because it doesn't follow the FAA guideline of VLOS (visual line of site) flight. They say FPV (first person view) flying beyond VLOS using the iPad view isn't safe, but the majority of us do it anyway. I simply disagree with the notion FPV isn't safe if you're in rural or mountain areas and keep the craft below 400' AGL (above ground level). You'll want to have 2+ mile range eventually, at some point, trust me. So with that in mind, the DJI craft than can do 2+ miles are P3P, P3A, (P4 struggles for 2mi),
P4P, MavicPro, Mavic Pro Platinum, Mavic2Pro, Mavic2zoom. For your goals I recommend the
Mavic 2 Zoom, because the 2X optical zoom is awesome, and you really don't need the lower light advantage of the Mavic2Pro, or the higher resolution, not to mention the M2Z is cheaper, if you can afford it. For your goals I think top speed capability may be important, so keep that in mind.
I just sold a used P3P that may have fit your needs perfect. It sold for $500 with 4 batteries. I'll miss that drone.
