in terms of FPV gear, you will need a camera and a vtx, most of the time they are seperate items. If you are looking for something basic, quick and easy, this AIO micro system (similar to the ones on your Whoop) is a really good option. Its 200mw (an upgrade from the typical 25mw) so the range is really solid and comparable to other systems that are larger seperate units. The camera is also really good for such a small size, maybe even better than some of the runcams I have. I have been using this on my Strix Nano Goblin with a TBS crossfire system and gotten well over a mile away (open air in a low RF interference area) My point is that its an impressive performer at the form factor and price it comes in at.... not to mention you can run it off basic 5v from the RX (solder up a Futaba female to micro JST female cable) and thats it!!

If you are looking to get a seperate camera/vtx, I would recommend the RDQ mach 3, a great performer (I have 3 of them
) with 1000mw output power and smart audio, but also at a steal of a price.

you will need a camera as well, and don't skimp here... this is your view, your connection to your aircraft, so having a low quality camera can greatly degrade your flying experience.
My personal favorite is the Runcam Phoenix 2:

Finally, don't forget an antenna. This greatly depends on the flying environment you plan to be in, as well as what you currently have on your goggles/monitor. RHCP Omnidirectional is the most popular, heres my favorite:

If you are looking for something a little bit towards the cheaper end of the spectrum, here's some options:
