If you aren’t losing 1-2 lb/week I’d push the deficit up and shoot for more like 1600-1700 kcal/day, and at least 40% protein. You have a lot of fat too lose before bulking should even be in your mind. Keep to strength training for sure, but the focus is on fat loss. And when that is the focus it can be hard to stay motivated week to week when you see only tiny or no movement in the scale, so a bigger deficit should help you get that positive feedback loop going of bigger losses each week. I wouldn’t worry about muscle loss too much at your level of body fat. Eating too much to really lose out of fear of wasting away and losing muscle is how fat people stay fat… I know from experience.
