Post-tamoxifen and Lupron - Removing ovaries with hysterectomy or not? ER+/PR+/HER2-

I was diagnosed in 2020/age 40 with ER+, PR+, HER2- breast cancer. Unilateral mastectomy; no chemo/radiation; I finished my 5 years of Tamoxifen in September... and felt fine on it. When I stopped, I felt like I was on a crazy hormone rush with breast pain in my remaining side, which was scary.

Then, I started having bleeding without a period for over a month followed by a very heavy period that lasted weeks. Ultrasound > Gigantic fibroids + new uterine polyps. My uterus is as large as a 4 month pregnancy. My only real course of treatment is a hysterectomy because I can't have hormone therapies (ER+/PR+ breast cancer history).

I *assumed* I would get my ovaries out to reduce the estrogen floating around potentially growing cancers since I'd been on an estrogen blocker for 5 years, but my oncologist and two OB/GYNs all say to keep my ovaries because of the potential of severe surgical menopause symptoms (that can't be treated with HRT), bone loss, cardiovascular disease, etc.

I don't know what to do or think at all. My gut says to remove my ovaries/get rid of the estrogen. Everyone aside from my doctor seems to say, "Get rid of them!" so I don't end up with ovarian or other cancers later.

I don't usually go against my doctors' advice and am scared of these "severe" surgical menopause symptoms... but I've been hearing the same symptom list for 5 years now and have been OK so far... Will the "severe" menopause symptoms be worse than 5 years of tamoxifen + Lupron… ? Anyone been in this situation and have some advice/thoughts/experiences to share?
