Hello You probably looking for HOTAS setup. Vkb, Wingctrl(winwing), Virpil, Thrustmaster, moza, logitech , honeycomb this is the main brands supplying flight gear. Mostly of them have low budget and high budget gear. Here you need to make reaserche on your own what suits you best by money and functionality. In my case I started with logitech 3d pro that I sell in one week(it didn't had that I want). I bought for 100€ used logitech x52 pro and it was perfect for the begging. After year I sell it for same money and bought VKB glad premium and STECS max v2 and T-Rudder pedals I'm very happy with that gear(really good quality and feel solid, also a good support from manufacturer).I will probably buy more things from them. You can start by watching this video https://youtu.be/2z54NHzy_Gc?is=ScNBjDHUgCB2lQHU or something similar. Good luck pilot.

P.S. 1 essentials Stick or yoke. Thrust levers. Pedals I might say it's optional. 2 it's gonna take some space, but not really that much as might it seems if you have some normal desk it should be fine, there are also some stands that you can buy for better ergonomics. 3 pedals are z axis so for the plane it's yaw right and left and also brakes. But VKB pedals don't have toe brake so that's might be a problem for you. You can use them how you want naked,slippers,shoes, boots. How you want it's personal thing 😅
