Help! Which Repayment Plan to Switch to?

Would appreciate some opinions.

All loans dispersed before 2014, repayment started on/around 2013/2014 after grad school. Work private sector, AGI %215,636.

I am wondering if I should switch to an IDR plan for my fed loans because I see these plans can result in forgiveness after # years of payment but I’m hoping to keep total loan repayments across both public/private below $1,500. (I expect to pay off both private loans within the next 3-5 years though so a short period so I am OK w/ going above that 1.5k goal for a short period).

Which IDR plan would you recommend for my fed loans and why?
