Ok on standard array you do not have a better wisdom with a bonus to Wisdom:I used standard array... Sage per background video is Con, Int, Wis
S15, D12, C16 (14+2), W14 (13+1), I10 ,CH8
Now with the +2 in Strength
S15 (13+2), D12 ,C16 (15+1), W14, I10, CH8
So it is exactly the same Wisdom in this non-optimal Barbarian on point buy. You are not able to percieve or resist mind effects better. It is exactly the same ability to do that if you keep your 15 and 16 in strength and Constitution respectively.
So yes there is no way on point buy or standard array to have a higher ability to percieve or resist mind effects if you start with a 15 Strength and 16 Constitution.
