Letting go of Top Pair & Two Pair here?

Hi Poker Friends!

Hand 1) Would the best line here be to fold river? Especially after flush completes? How would you play this better?

Hand 2) Fold on river shove with two pair here? How would you play this hand better?

As usual, I always appreciate any input/feedback. Thanks in advance :)
