This hand is probably good enough to just flat pre, and you can use hands like A4s or 76s to 4bet, Although there's nothing inherently wrong with this I don't think.
I mean I don't think most people have the balls to bluff this board often enough at NL10. He might not even have any bluffs in his range when he flats the 4bet. Like a lot of low stakes regs will fold all their 87s type hands that they may 4bet, and just flat those 99-QQ and maybe AQs type hands they 3bet pre. If they even 3bet 99-JJ or even QQ.
You also do have some better hands to call here, like AA/KK and JJ/QQ, assuming you check this flop 100%, which I think you probably should on this flop.
