Hysterectomy and ovary removal with HRT: Pros and cons

I’m 44 and having heavy and irregular bleeding with severe cramping outside of my period, which has always been painful and is getting worse. Diagnosed with endometriosis at 24 and have had excision. I also have PMDD and menstrual migraine. I do not tolerate progestin-only treatment and feel best around day 5-7 of my cycle, when estrogen increases and progesterone is low. Combined hormonal birth control worsens pelvic pain. What are the pros and cons of getting a total hysterectomy with ovary removal but then taking HRT after (estrogen and possibly testosterone and micronized progesterone). Want to protect my future health but also get rid of the severe and unpredictable pain and bleeding (because nothing else has helped).
