Try:
=IFERROR(INDEX(SORT(SORT(FILTER(MATRIX, (LENGTHS>length)*(WEIGHTS>weight)),1,1),2,1),1,3),1)
, where MATRIX, LENGTHS, and WEIGHTS refer to the data on the right, whilst length and weight refer to the cells containing 80 and 450.
Just saw you said H6 was what I referred to as length - if so:
=IFERROR(INDEX(SORT(SORT(FILTER(K6:M11, (K6:K11>H6)*(L6:L11>H7)),1,1),2,1),1,3),1)
in H8.
