Villain is defending 97% and has CR around 40% of flops over small sample and has barreled turn a little merged previously ie middle 2 pair and FD.

So based on that I think a good way to play our range is to BC all our sets+top 2 and jam turns, and also do that with some of our semibluffs. This hand does have much more SDV than our other semibluffs, but I think potting turn is ok as we could get better to fold and can protect vs worse hands/draws too.

What do you think of game plan, and what do you do on river now (SPR 0.85ish)?

call turn for the reasons you stated imo, you have plenty of sdv, and raising here is kinda bluffing with the best hand most of the time. you also want aggro villain to repp your hand otr imo.
that said, raising can´t be bad too for balancing reasons and can hardly be a mistake since we got so much equity, but i prefer a call for above reasons + still realize our positional advantage instead of prob getting it in as a slight underdog vs his gii range. we also don´t need to protect against much.

as played, i don´t see how we lose. he prob doesnt have much of a calling range on that river, but still we are prob gonna bluff shove some missed draws, so clear valueshove imo, i think he´s gonna level himself often enough into a call to make up for the times we valueown ourselfes whichs should be extremely rare imo (basically some 5xxx)

I agree with everything sauhund said...def like peeling turn and as played shoving river although its seems neutralish to marginally +ev value wise its great for balance
