Happy to hear that it went well and now you have some hands-on experience. Good feeling, right?
From here it can only get better as you gain more and more experience. Your starting points sound good to me, I know the "Mister May" rig as well. That's a good one. The others you mentioned are the right choice to highly likely achieve a good sound for gigs.
Given how well this went, I may end up switching to Kemper full time, and keeping the tube amps at the house for practice and profiling.
That's the way I did it and meanwhile I am using the tube amps rather rarely. I just fire up the Kemper at home as well. Basically it is my central sound tool whereever I go and whatever I do. Big advantage: I can always tweak and save what I have. Can't tell you how much I enjoy the consistency of the sound and all around it
