If you purchase a BNF (bind and fly) / prebuilt FPV drone, the quad will fly fine without playing with any of the complicated settings / options within BetaFlight. You’ll only need to calibrate the compass, bind and program your controller movements before your maiden flight.
There are loads of other YT content creators too, if you prefer other creators, however I found that JB’s videos were detailed enough to follow without blowing my mind.
