What will be the best setting to fly indoors?
Just in atti you can do a lot, but if you put the p4p+ on beginnermode you also get a lot of "security"
Any suggestions?

A good suggestion would be to not attempt to fly indoors.
Stay outdoors in a large, open area where there is nothing to hit and no electrical cables and elctromagnetic effects to upset your compass.

Generally, the beginner mode requires good GPS signal, so the motors can not be started indoor. I would not suggest to fly indoor as well.

I had a yuneec typhoon q500 ( ugh )  and could fly indoors in a big production hal for promo film.  no problems. Before that i used to fly an hand made hexacopter with  + naza / + dslr  / also full manual indoor.  
With all the sensors of the p4p+ i thought it would be even more easy.

If you are familiar with ATTI mode flying and with the Visual positioning sensors, you should be fine in a not too small hall.

I wont recommend doing it indoors, and plus you need strong GPS signal before you can even start your motors on your drone.

If you fly in tripod mode, that worked nice for me.

Indoor = broken lamp, broken windows, terrified dog ,& really mad wife.  Not worth it.

Lack of GPS signal doesn't prevent you from starting the Phantom.
People launch in atti mode all the time from locations without GPS
