I think, you need the combination of formulas. The answer is:
={QUERY({A:C},"select Col1, sum(Col2) where Col1 <>'' group by Col1"),{"filtered sum";ArrayFormula(IFERROR(VLOOKUP(UNIQUE(FILTER(A2:A,A2:A<>"")),QUERY({A:C},"select Col1, sum(Col2) where Col3 ='yes' group by Col1") ,2,0),0))}}
Explanation
It's not hard if you'll take it by parts:
={basic query, {"header"; vlookup(a, help query, 2, 0) }}
Basic query
QUERY({A:C},"select Col1, sum(Col2) where Col1 <>'' group by Col1")
It's simple, I've used Col1, Col2... notation to make it work with any range.
Vlookup
IFERROR(VLOOKUP(UNIQUE(FILTER(A2:A,A2:A<>"")), help query ,2,0),0))
We count sums with criteria (c = 'yes') in the help query.
UNIQUE(FILTER(A2:A,A2:A<>""))
part of the formula gives you a list from column 'a'.
Help query
QUERY({A:C},"select Col1, sum(Col2) where Col3 ='yes' group by Col1")
Here you may enter any conditions what you want. In this case it's Col3 ='yes'
Google Query Language inferes the column data type and the values that are not of the inferred data type are ignored.
TRUE and FALSE are booleans but OTHER is string. Depending on the order of the values of one type or the other are being ignored.
