Need advice on attic insulation

I'm in the very early stages of planning an attic renovation in an 1800s house that already has half of the attic finished, likely sometime in the early 1900s. I've researched most of the potential work to be done and can handle it in general, but the question of how to insulate is driving me insane; I honestly have no clue what to do to solve it.

I'm in the very early stages of planning an attic renovation in an 1800s house that already has half of the attic finished, likely sometime in the early 1900s. I've researched most of the potential work to be done and can handle it in general, but the question of how to insulate is driving me insane; I honestly have no clue what to do to solve it.

Some key points:

- Located in New England, roof is <5 years old with regular black architectural shingles

- The house has no soffit vents, no ridge vent, only 2 gable vents and those aren't particularly large.

- The attic has windows throughout, as if it was originally planned as a 3rd floor but stopped before finishing, there's a normal staircase up there and no door or anything.

- The headspace is remarkably high, ~10ft+ in the middle and the roof is extremely steep so the useable proportion is large.

- No insulation whatsoever, not even in floor

- Electrical has been run but not finished, i.e. no outlets.

My biggest issue is how to properly insulate this? I really don't want to use foam because, although the roof is relatively new, I don't want to have it be a huge issue repairing any leaks. But, since there aren't any soffit vents or a ridge vent, I can't do what I originally planned which was rafter baffles with regular insulation. Any suggestions? I'm at a loss and definitely don't want to create a nightmare moisture scenario.
