You can go to Preferences and enable the "Always Show Full 3D Transform Gizmo" which will give the option to rotate in 3-axis.
Also, you can use the Lay-Flat feature under Edit (Place Surface on Bed) as well as double click the model and use the model settings window to rotate.
Personally, if I ever have a rotation that is more complex than rotating around the Z-axis, then I just use the Edit --> Place surface on bed option. That is way quicker than my trying to manually do it.
You can also double click on the part and enter a specific angle if you know it's exactly 90 degrees around the Y-axis or something like that.
