Typical Treatment Option Question

My recent biopsy revealed Gleason 9. No lymph node involvement or bone. CT scan was clear for chest, abdomen, and pelvis. No PSMA done. There is Cribriform and Perineural invasion. I attended an information Zoom yesterday and tried to get a handle of what treatment path will work best for me. Albeit healthy, I'm 84 so RP is probably not an option so some kind of radiation and drugs. It's a month before I see my Urologist and I want to be prepared. I wonder if ADT be a given? If so, what drugs (and how many) would I start on? Would radiation be done right away? EBRT or SBRT? How urgent should I push to get going on this? Has anyone been down a similar path with a similar age and aggressive cancer diagnosis. I know we aren't doctors but I guess I'm looking for a typical treatment plan. Just reaching out since I am a bit overwhelmed.
