Are you handloading or buying ammunition?
If you are buying, then whatever is cheapest will do. I am at present shooting WWB 115 gr FMJ while my reloading equipment is in storage awaiting completion of a new house.
If handloading, a lot of shooters prefer subsonics with a 130-147 gr bullet at a velocity to give power factor 130-132. My last load was a 135 gr Billy Bullet (moly coated lead) at 980 fps.
It doesn't matter nearly as much as you might think while you are "about to start to learn how." You have a lot of technique and rules to learn before fine details of ammunition matter.
