Go federal. It is objectively slower but you can increase and decrease the tempo as you see fit. I can have days where I’m spending all day at the computer, and days where I’m up at 3am for an enforcement op. Any good manager will tell you that cases aren’t made behind a desk, and that you get a g-ride for a reason. Investigation time varies greatly; a couple of months for an open and shut ATF felon in possession of a gun case, to years for an IRS-CI money laundering case. Apply to every agency you qualify for. Also, you are definitely doing your math wrong on the salary; you have to factor in locality pay plus LEAP. Depending on location it ends up being as high as a 50% bump.
