This is an oversimplification but I state this just in reference to your question on BMR. Couple other things to consider, when dieting below maintenance a Keto diet will usually require a "refeed" at least once a week while a carb cycling method addresses this as well with a meal every 3-7 days that will usually be around 1,000 calories over TDEE. This purpose of this is to avoid the exact scenario which you describe above. Also, most cutting diets are 8-12 weeks long which will normally be too short for a significant lowering of BMR.
I am still a huge proponent of cardio I have just changed my views on the most effecient way of doing it. I spent years doing 30 minutes fasted in the AM followed by 30 minutes PWO, light intensity (120-130BPM) on both 7 days a week. After much debate with someone smarter than me I reluctantly gave in and tried the HIIT method. 3 sessions a week, 30 minutes each. I am can attest that the HIIT style has kept me much leaner and gave me 5 1/2 hours a week of my life back. My wife switched as well and had the same results. When in contest prep we both start adding in some light intensity sessions as well.
