First off, congrats on your loss! That's a pretty drastic difference and most people wouldn't have the stones to undertake such a process in the first place, let alone keep it off. Hats off to you, danradin.
You could definitely get lean following a RFL type approach, but I don't think that's optimal from a big picture aspect with regards to strength/metabolism/eating habits/sanity. I think we can attack this from two different angles, one of which is simply building a bigger motor (strength, muscle, etc) and the other is dialing in the diet. I don't have any magical nutrition tips other than trying to bump up your carbs a bit and regulating your fat. I think that the extra carbs will help your training and recovery and fat will be a large enough component that your hormonal processes are more than taken care of.
Big Picture: Find the sweet spot where your waist is getting smaller and your weight is either static or slowly decreasing. Since we're on a strength board I'll tell you that you'd likely see better results from pushing your weight up a bit, but adding extra fuel slowly. On the other hand, if losing the last bit of BF is your ultimate goal then we'll go with that.
I'd have you switch up the conditioning to 2 x HIIT per week with 20-30s ALL out efforts with 4-5x as much rest (ex: 20s on, 140s rest) x 7-9 repeats. Ideally these would be on "off days" but you can do them on M and F as well.
Macro-wise let's start out at 250/200/90 except on Monday and Friday, which will be 230/360/80.
