As you probably know, having got this far, everyone's response to T varies.
If the temper stuff concerns you, you could try taking some anger management. I didn't notice any difference in my temper except that it does seem to flare up and cool down more quickly. I don't get stuck on stuff.
You may be able to adjust dose to deal with the effects on your sex drive, so that if it becomes a problem for you, you could dial it down a bit.
And the bad news with male pattern baldness is that it means that just like bio guys you could lose all your hair, some, or none. Have a look at males in your family, that may help you guess your chances. It is thought to pass through the mother's line, or be x-linked, but given that we have an x from dad's side, probably a good idea to have a look at dad's family line as well.
And just like bio guys, some of our singing voices survive the change, others don't. I've been fortunate with that and my singing voice has actually improved. It took a long time for it to stabilize though, especially the upper range. I went from alto to bass and can now sing a lot of the tenor range, although it's taken a few years beyond the point where my speaking voice stabilized.
Haven't noticed increased sweating, but I do smell worse than before when I do.
You can't know what effects you'll get from T, but you do need to be ready to accept the bad if they do happen. That's part of getting emotionally ready for it. If it's any consolation, guys who are born male have many of the same effects and they just have to hang on for the ride.
And, as far as potential negatives, there's also the possibility of having major struggles with zits. That was the one I was most concerned about because I didn't want to be a 42 year old with the complexion of a teenager.
