Radical Prostatectomy vs. Radiation therapy?

I'm a 65 year old very active workaholic male. I have a 100+ year old restaurant that is/was family owned and operated. Now there is just me as the remaining owner/operator. I'm also a part time professional stage technician (a passion of mine) and this job involves heavy lifting work.
I was diagnosed with stage 2b prostate cancer, 4 lesions 3+4=7 with a decipher score of .96, which I'm told is very high risk to metastasize. I had a PSMA PET scan and it shows, fortunately, that, at this point, there is no spread.
I'm very concerned about all options and their side effects. Biggest concern regarding surgery is incontinence, second is ED followed by the necessary time away from my business, which I am integral to the daily operation.
Radiation seems, with the issues stated above, like the best option, however I'm very concerned about long term health of other neighboring organs and the inability to due surgery post radiation if a reoccurrence should happen. Any thoughts/advice.
None of the listed concerns with exception of incontinence will prevent me from doing what is necessary for best long term outcome. Appreciate any thoughts and/or advice. Thank You, Michael
