First of all congrats for your successful result 🙂
If you want to pursue for ICAEW also then taking P6 will add one more paper in exemption column..
And it depends upon your interest and strength also, if F8 and P2 were your favourite subjects then P7 is good..
For F5 general impression is that this paper is just focused of F5.. It has good syllabus though..
Well I took P4 and P7.. I liked F9 very much and found P4 very interesting but very tricky and difficult one 🙂 and after all I managed to pass these papers ..
