I made a rough parts list with everything to get you up and running:

The motors for your build should have between 2300kv and 2800kv there are a lot of choices out there and its like most of the things in the RC world you have to decide how much money you want to spend.

You will also need ESCs (electronic speed controllers). I recommend going for the xml20a from DYS or similar.

as flightcontroller you'll have a broad variety of choices. You could use a cc3d and then flash beta flight on it which is very cheap, You could also take a look at one of the newer FCs which have integrated OSD (on screen display) and/or video transmitters.

You better make your own decision there.

Different flavours of Flight controllers:

Integrated SD-Card Slot to record flight data:

Integrated OSD:

As PDB (power distribution board) I like the Matek PDB with integrated Lipo warner (Low voltage warner) which also is switchable by the transmitter if you can't find the quad after a crash.

As camera take the 700tvl fatshark camera (because of the size)

I tested a few other cams in similar size and all of them had a very dark picture.

If you choose an FC without video transmitter you can get one of these. They are very small and work great for me (these are also very cheap).

If you want an OSD the micro minimOSD is a very versatile choice. You can monitor your batterie voltage, receiver reception and many more.

Additional parts will be

video goggles,

(This is a hole category in itself but I will leave a few links here)

Things that matter with FPV goggles are FOV(Field of view (higher is better but stay between 30 and 50 degrees for the best flying experience)) and screen resolution (higher is better of cause) and the price.

battery straps,

LiPos,

Get a few 3s Lipos if you are a beginner, but not to many you will be flying 4s sooner as you think. Also do not buy LiPos with a C-Rating lower than 40C.

LiPo charger,

FPV antennas

(Make sure the connector fits your video transmitter (RP-SMA/SMA))

A rule of thumb is don't take the cheapest stuff and start by imitating other fpv pilots.

This is much information for one comment but if you want to build a quadcopter some reading and learning is involved. With the list of products I recommended you have a good starting point for your first build.

If you have any further questions don't hesitate to ask.

Happy flying
